>An open market will always favour the landlord,
Why don't you try being a landlord if it so easy? Not only do you have to capitalize to the tune of hundreds of thousands of dollars (or get leveraged to that level), between costs and taxes, your profit rate is going to be pretty tepid. It's not easy money, trust me.
>We've been trying these approaches for centuries now, and they always end the same way. There has never been a "free" market which hasn't vastly increased inequality of opportunity across the population as a whole. Why is it so hard for proponents of "free" markets to accept this fact?
Because that's not true. The free market has been the primary and pretty much the only driver of prosperity. And you cannot legislate prosperity. There is no magic combination of minimum wage, rent control and welfare that will increase jobs, income and wealth of the individuals.

Every communist nation thought it could 'educate away' human nature and brainwash to population into good communist automatons, and every time they tried it led to a humanitarian crisis. It's seems to be a core property of communist thought that human nature is completely flexible and can be shaped in anyway to make communism actually possible.
