Right, the government should make sure housing is available at all levels. Presumably it’ll have to do very little to make sure luxury housing is available.
If there’s ready supply at the low and middle end of affordable for all family sizes up to ~12, the program will have succeeded in my book. I would not want so much a single taxpayer dollar go to “improve” the situation from that baseline to one where luxury housing was also readily available.
I do not support government assurance nor ownership for the high-end or luxury levels of affordability.
