An unreachable tier of society indicates a fundamental social injustice. They're in the top 20% of wealth...not intelligence, or in any other factor making them deserving of it. Some of them did work hard, and probably deserve it if you consider hard work deserving of it...but, some people worked harder and didn't make it, so it's not a 1-to-1 equation. So there's a huge element of luck, which is kind of like a slavery for the bottom 80%..just like, you're born with one skin color (luck), you're in the upper class, and own the unlucky people born with another skin color.

Generally, we try to equalize the brutal laws of nature and offer equality of opportunity and try to remove blind, dumb luck from human life...with health care, with insurance, with social equality...sometimes, we succeed, but this is a failure.
