I disagree. When the environment you grow up in has conditions that hinder development, you are at a serious disadvantage. FOR EXAMPLE: Many of the less well-to-do neighborhoods in the Washington D.C. area have gotten their drinking water from the Washington Aqueduct, which has recently been found to have a lead content higher than the acceptable levels (which are too high to begin with if you ask me). What effect will this have on the children growing up in those neighborhoods? Do they still have that same potential to do well, or has it been diminished significantly?
Don't get me wrong, I fully agree with the philosophy of working harder if you want more money. I have done it. I grew up poor. Not everyone can, and it is arrogant to say that everyone can accomplish the same thing, because it is simply not true. You will ALWAYS have people under the poverty level. When you have a society where the people adjust their income to compensate, the poverty level changes. It's called INFLATION. When everyone can afford to pay more money for something, the price gets raised. There is no way around it. There will always be people doing the most horrible jobs for the lowest amount of money, and some will even be happy to do them. There will also always be unemployment. No way around these things (in a capitalist society). It doesn't matter how hard everyone works.
