It's the other way around. In a situation where there is finite construction infrastructure or land it doesn't matter what you build, affordable housing will decrease because pricing power allows price raises for all building types. The good news is there is basically no place in North America where there is a finite construction infrastructure or land causing housing shortages, except for maybe very low population remote areas and maybe Manhattan. The vast majority of shortage is driven by bad government zoning and approvals policy (looking especially hard at you San Francisco). If you fix the policy in a way that developers will be reasonably sure it won't revert back and be used to punish them for what they did under new policy, your shortage problem would sort itself out in a decade or two as the massive building boom led to a glut and lower prices.
