It has always been true that men were expected to work. They were expendable, they had to be useful. Furthermore, there was the peer pressure of the other men of the tribe.
In terms of the expected to work part, not much has changed in today’s world. In times’s past, work could improve a man’s position with respect to the single women. This is still somewhat true, but not like it used to be. Destroying the Evil Patriarchy did that in. Work also used to be a means to garner respect within the community. That is still a bit true, but it has faded also.
If you are a man, nobody is too eager to support you financially. So work it is. But why work? Other than to support yourself and pay taxes, society doesn’t really have that much to say. So much of it is up to you. What will you do?
