Housing prices getting too high is the reason why many people can not afford any housing. So the housing market needs to follow the free market rules, be allowed to fall when it has to, and not be interfered with or propped up by the government.
By propping up housing prices, the government is helping out those who speculate in the housing market, letting them make a lot more money from their real estate investment than they should, and kill a lot of working people’s American dream in the mean time. This is the reason why the American dream has become impossible for a lot more working people. This is also the reason why the US economy is not growing much.
Donald Trump may not have liked the housing market crash for a noble reason. But he was with a lot of Americans in this matter. I find it regretful that he is not educated and articulate enough to offer an effective rebuttal in the debate. But being educated and articulate while being unintelligent and unthoughtful makes a presidential candidate even less qualified.
