Life today is easier and more comfortable than it was when your grandparents were children.
Although some people believe that life today is easier and more comfortable than it was when our grandparents were children, but it seems to me that the world today is more complex than before and proportionally our needs and businesses are completely different toward our past. On the other hand, comparing our life today with our ancestor's is not practical.
First, for having a better illustration about the issue, you can imagine our grandparent's life in fifty years ago. When a man and a woman got married, the husband's and wife's duties were completely determined; the man had to work out of the house and earn money while the woman was working at home and taking care of children. So the work division system was pretty determining for preceding a family.
