Your argument seems to be that a few people get money while doing nothing to earn it, or have never done anything to earn it. Seems pretty absurd to me, unless you can show me how that works.
They can inherit it. Take, for example, the Walton heirs. According to Wikipedia "In 2010, six members of the Walton family had the same net worth as either the bottom 28% or 41% of American families combined (depending on how it is counted". They didn't build Walmart. That was done by Sam and Bud Walton, their ancestors / in-laws. They just own shares in it. Christy Walton, for example, has a net worth of $36.7 billion. Can you explain to me what she did to
earn that money apart from marrying John Walton, the son of Sam Walton?
The U.S. Constitution addresses infrastructure, a limited government environment in which businesses can thrive etc. but it doesn't address things like health and education and safety nets, because there would be too many differences of opinion about just how those things should be done, so it leaves it to the states, or to the people, free to address those things privately, with things like private charities.
There are lots of things the U.S. Constitution doesn't address: how big the federal budget should be, how large the Army should be, how many people should sit on the Supreme Court, etc. This is not necessarily a sign that this is left up to the states or the people. Sometimes what it means is that it's left up to Congress to pass legislation on these subjects.
