Please show me that evidence, because I have seen otherwise, and a basic understanding of supply and demand leads to the default assumption that increased supply will lower costs.

The ONLY way to make housing affordable to make market rate housing affordable. That means you need to build enough that they are forced to lower prices. Couple this with a vacancy tax to prevent manipulative property management tactics, and there is no logical reason why increased supply would not lower prices.
