I honestly know very little about the Constitution. What I'm arguing is, if it is as you are saying, that it is entirely unconstitutional for the government to do anything about the balance of buying power in American commerce then we have a very flawed and doomed to failure system of commerce.
In an entirely unhindered free market business only thrives among the most wealthy. Because there is no business incentive to build a car, for example, to chase the fewer dollars that poor people have. That would be a moral decision to do that. Despite what so many Americans think, America is NOT a Christian nation in deed, only in word. Therefore it is necessary to build monetary incentives into the system to make Americans do moral things. You have to speak the language of business ($) to get business to do something.
In the end, the only thing I can think of why anyone would resist what I said about the necessity of government to fairly and honestly make it so goods and services are attainable through a 40 hour a week job, alone, is.........greed. And that is precisely what I see in the right wing. The thinking being, why should I build a car for 20% of the population and make less money when I can continue to only build cars for 80% of the population and make good money.
