There should be no limit on how much anybody makes, because the more income the more tax revenue. Of course, billionaires and millionaires should pay a higher percentage of their income than poor people. The only question is how much higher should this percentage be?
Should poor people be imprisoned to be penalized for their bad financial decisions, such as those that led to bad credit? But then they would be taking from everybody while in prison, including billionaires.
Conservatives are strongly opposed to government welfare and want it abolished, because they believe far too much of it is given to deadbeats, who are too lazy to carry their full weight in society. It's viewed as immoral to make deadbeats dependent on government to live. That is where some of the Republican opposition for being against more Medicaid for Oklahoma comes from. But end welfare and you'll only have more crime from theft and pushing illegal drugs.
