Fallacies, lies, and generally ignorant opinions include * Pretending the US was a more market-oriented economy in the past (which is not true)
* Comparing the housing situation 100 years ago to that of today. There are many reason why america in 1917 is very different than the america of 2017
* Literally cites a Wall Street Oasis forum post as a source on why we should not subsidize housing for the poor
* Income inequality is (obviously) a huge component of housing not being affordable (especially in urban centers) and this is dismissed using an obvious straw man argument.
One of the biggest housing subsidies is the mortgage interest deduction which is almost entirely captured by wealthy homeowners and financial institutions. It also definitely pushes up housing prices. If the author of this post had any knowledge of the housing market they would have brought this up.
