I think it's a slave system because the most expensive part, land, is monopolized by government, local and federal, and I think it's done to protect existing home values which are, as you know, largely owned by banks. It's true that most folks consider their home their most important investment, and I think that norm is also part of the plan. Interestingly, a side effect is that it also helps drive the industry's desire for immigration, which props up demand and gives liquidity.
