The problem being that you have restated your position without demonstrating it.
It simply is not true that conservatives desire to keep people poor. Statements to the contrary are simple ad hominems, and demonstrate an inability or unwillingness to address the position without attacking those who hold it.
And your “simple, obvious fact” that wealth is limited is neither simple, obvious, nor a fact.
Consider Bill Gates, the richest man in history. Where does his money come from? The sale of software. Where did that software come from? Somebody made it up from nothing.
Who did Bill Gates steal his money from? If the supply of wealth is limited, he must have gotten from somewhere.
Or else, he made it himself. And, by getting rich himself, he made a whole lot of other people very rich, and almost everyone else a little richer. By creating a market for a product.
In the ideal capitalist transaction, both buyer and seller feel they got the better of the deal. The seller got back enough to make a profit, and is thus encouraged to continue. The buyer got something that he valued more than the money he used to buy it.
Thus, the economy is enriched by the difference each perceives between what he gave and what he got.
It is simply untrue that a capitalist/conservative society requires poverty. Just the opposite - more rich people (in real dollars) means more available capital and more markets and more opportunities.
In 1900, two thirds of the US population lived below the poverty line (in constant dollars). That enormous decrease in poverty has not fueled anything resembling a collapse of capitalism - exactly the opposite has occurred, where communism/socialism has collapsed (in many, welcome cases) and capitalist societies like the US and Western Europe have experienced a huge increase in their standard of living.
As long as we are distorting each others’ positions, how about this - in a conservative society, if you make money, you are allowed to keep it. In a liberal society, after you take all the risks and do all the work, Big Brother steps in, takes it away from you, and gives it to someone who has nothing to deserve it except fail.
Conservatives want to reward success; liberals want to tax it. Conservatives want to discourage failure; liberals want to subsidize it.
