Many work primarily for money.
But this is not everyone's only motivation. Many people advise work, even if their partner fully provides for the family or there is passive income. After all, work is not only personal money, but also development, self-sufficiency and the opportunity to improve skills. 

It is important to be independent!

I never wanted to be financially dependent on anyone. This is very restrictive. All I see is how unemployed women, including my friends, become dependent on a man and cannot financially afford a divorce because they cannot afford children. I will never advise my daughter not to work if she asks for my opinion.

I am in favor of people doing what is most convenient for them. From my own experience, if you don't work and someone supports you, you are in a vulnerable position and if something happens, you will be easily manipulated. Therefore, I am in favor of every person being successful in one way or another and finding an opportunity to receive money for their work.

Does anyone really think that it's okay when only one person in a pair works? It seems to me that this is ok only when one of you is on maternity leave. It's not even about money, it's simply about respect and self-respect, and about security too — for example, if one of the parties wants to leave. When only one person in the family earns, it immediately puts the second person at risk. Your own work is not only your own finances, but also a certain independence.

A non-working adult is at risk. Everyone decides for themselves, but I don't understand why, in a world where everyone is independent and responsible for themselves, make such a risky decision not to work.

You need to be prepared for force majeure

No one is immune to force majeure. Many may think of illness or tragedy. Alas, life is more primitive - a new love for a earning partner can happen absolutely suddenly. And here no one will want to help with the start-up capital in a new life.

There is a partner today, but not tomorrow. Where to look for a job if you haven't worked for twenty years? How to live in old age if the pension is the minimum wage, and you have not created passive income either? According to statistics, most housewives do not think about passive income, fully trust their husband financially, and he can write down all the property to his relatives.

Now you are sitting full and warm, all your needs are covered by magic. And then, instead of you, the master of your life – in fact – finds another person. It doesn't matter how, why, for what. Or just leaves you. Or he does things that are impossible to endure, but you live at his expense, where to go. Whoever pays, orders the music.
And what to do in this situation? Isn't it scary and hurts your healthy pride that at any time you can leave a hypothetical palace to live in a cowshed simply because you will not be able to maintain your life at the same level on your own?

Work satisfies the need for excitement

If there was an opportunity not to work, I would still keep a couple of clients. I am a very adventurous person. And this excitement needs to be put somewhere. Machines with toys do not really help, they get boring. Serious gambling for big money – well, what the hell. But litigation is the best.
Unlike roulette, you can choose the option with the maximum possible win: give up things where there is no chance, and take what the chance of winning is high. And here several needs are immediately covered: you can put the excitement somewhere, you can help someone. The main thing is not to take on things that contradict my principles. And it is also a good exercise for the brain, you can avoid degradation.

You can spend money on your desires

I love to work, my little sweet money is much better. But I don't want to work like a horse.

Work helps to develop your interests and realize yourself

A friend of mine arranged an experiment: his wife takes care of the household and the child, and he works. The motive is "we live so comfortably."
Seven years later: "We're getting divorced. We have different interests, she doesn't want to go anywhere, she only sits in the country and takes care of the house, and I want to travel, see the world, learn new things." There were no such problems with his wife, while she worked, communicated with people, there was no stagnation and everyday life in her life - which, by the way, she likes.
I warned you that this would happen. And so it happened: after another "I don't want to go anywhere", in the end, there was someone who manages to do everything and wants everything, even earns more, but at the same time is not tired of work, children are due.
People should be engaged in at least something social. There is no sociality in everyday life, only rottenness, degradation and stagnation.

Of course, everyone lives as they want, and usually all this is discussed with the partner on the shore. I understand the meaning of a household in families with several children. But if just two people live together, I vaguely imagine:
What can be interesting about a theorist who, perhaps, due to a lot of free time, reads a lot, but in practice does nothing but do household chores?
How can you be sure of such a partner? Something has happened – and what will this very theorist do, who in life has never held anything heavier than a frying pan in his hands, as they say? I am referring rather to the inner core and the ability to take responsibility, to support in difficult times – sincerely, and not for the sake of giving pocket money as soon as possible.

Work is not only money, but also a way to keep a person busy, give him a sense of value and the opportunity for self-realization. There were so many betrayals because my wife just got bored.

My work benefits society, I am an engineer and a teacher. If I did not work, but only consumed, which, in principle, is financially quite possible, I would be useless for everyone, even for myself. Honestly, I can't imagine myself without work, I've got used to it all my life.
Another thing is that with age, you need to save yourself a little more: work, say, two or three days a week, if your income allows, or work remotely from home. But it's just boring without a job at all. I can't imagine what I would have been doing for years without working. No, of course, hobbies, walks, museums, travel, but not all year round! So you can go crazy from idleness.

You don't have to work. But you don't need to. Because a person must realize himself as a person, and work is one of the main means of self-realization.
If a person has other means of self-realization — for example, a mother of many children who simply does not have time for work, or a volunteer — then you don't have to work. But when this person has time, you need to start working.
