The whole system is by accident or design setup so everyone is in perpetual debt, if you're in debt you're essentially a slave to the system, there is only so much wealth in existence at any moment, the idea of supply and demand is a bit of a joke, a house costs only so much in materials and labour, on top of that you can add a reasonable profit for the building company but now the price must be fixed based on actual value, which is less than that added profit for whoever next sells it, like with second hand stuff if anything it should go down in value.
