That's right, expecting too much from the government will not be able to help our needs completely, and to be able to meet our own needs, of course, we have to do it ourselves, including by working hard, especially at a young age. At a young age we should work hard because it is something that will determine us in the future or our own future, if their youth is only enjoyed by relaxing then the possibility of their future will not be good or less good.
This is something that the young simply do not get, when you are young you are as healthy and as energetic as you are going to be, but they believe due to their inexperience that this is always going to be the case and they are mistaken, so they need to take advantage of that energy and time they have to try to build something out of themselves, that way once they are old they will be able to reduce their workload and still be in a good position.
I think most young professionals were just enjoying the things that they can afford while they still have the energy to do so, it's not that because they lack in experience. Working too much while you're still young would make you miss some things you can't do when you're older. I'm quite sure young people knew they need to work hard, though they don't have any idea how stressful life could be when you are in the adulting phase, that you'd even lost track on your work-life balance. Also, when you get older being employed in company, I don't believe your workload are reducing. Yeah there are promotions, but higher position means additional responsibility, so i don't think work load will be reduced in that case.
