because that goes against the concerns of the elites. the rich, who pay for the campaigns of most politicians (surely they pay for all of those who have a chance to win the post of president or prime minister), will try to squeeze every dime they can from everyone else, specially from the poor.

small to medium business won’t thrive because that would be another entrant in the market to split profits with the larger, more established business. they have already large advantages because they purchase raw materials and utilities in bulk, hence they can get a lower price and larger profit margins than the smaller, newer entrants to the market. still, they want to be sure that everything remains like that and therefore have politicians to keep things that way. the idea that new business will make a difference in well-established markets is an illusion.

as for property supply, well, land in our system is not a resource, but a commodity. take the real estate market for example: investors are buying property to serve as a financial asset, they buy houses when they’re cheap, rent them and sell for a profit when the market conditions are good for that. they don’t think of housing as something that should serve their primary purpose - as the place of living for families. they don’t want to lose value on their properties, and that’s why they have politicians to represent their interests and keep things the way they are. same logic applies in big cities where investors buy commercial buildings and don’t want to see them not valued enough - by not having people actually working on them. that’s why they’re so radically against remote jobs.
