Hello, DiamondChan. I, also, am of the belief that wealth/assets are not limited. However, if one took the opposing view that they were, that is all the more reason to work harder than others, spend less than others, and amass what limited resources that you have. As, then you have what it takes to "go for it", when others cannot.
I'm not talking multi-mult millionaires, or billionaires .. just John Q. Average ... and what he can do for himself and loved ones.
