I agree that wealth is not just about the money one has, but it also affects the lifestyle, social circles and activities. However, there are some things people can't and maybe shouldn't change (such as your family). Also, getting a fresh start doesn't mean you'll get rich, and of course there are different kinds of rich.
As for hard work, some rich people do work a lot, but there are also those who simply are rich by inheritance. Also, some people work really hard but are poor.
What I think is important is to understand what one wants from life and what one can realistically get. It's also great to enjoy the process and not push oneself for a result that may never come or may come at some point at a great expense and without the expected joy.
Because for poor people who want to get rich is really really hard.
When the poor have a dream to study or work abroad, his close people including his parents will say it won't happen because he's poor.
When the poor have a well paid job, his parents and siblings will ask for money because they see this "successful kid" as a money machine, it make him can't save his money.
We didn't even talk about how hard he try to change his life with no money, no relations, no good education, etc.
