My thought behind the regulated sales price on new builds targetted at 'affordable builds' (not all house sales) is that the current investment/price/profit balance for new builds is such that, in my experience, new builds are not what a reasonable person would describe as 'affordable'. Instead, they are often hundreds of thousands more expensive than the housing they are built near (looking at the new builds down the road from me and sighing). So there needs to be added pressure on developers to not build nothing but detached three story 6 bedroom houses, call it 'affordable housing', then sell it to buy-to-leters who split it into three flats and rent those out.
Contracting them to explicitly build housing within a set price range would mean that they have to publically agree to and meet a definition of 'affordable'.
But then there's still a need to shut down loopholes like stopping those houses being simply purchased and immediately resold at a higher price, so some extra constraints on the purchase/sale snowballs from there.
Hold on a sec, where did you get that federal minimum wage is $15? It's still $7.25, as it has been since 2009. Some states have gone higher, and Biden did some EO stuff to try and encourage higher pay in niche circumstances, but it's still $7.25 when all is said and done. (And then there's tipped wage, which is even lower.)
I should have double checked his claim! Not being American don't know your mw off top of my head.
