I very much agree. This is how I feel too in regards to this "abundance liberalism": some people think they can fix the whole country by deregulating zoning laws and tweaking a few numbers. It seems foolish to me. Whatever the solution is, I am convinced it requires (re)building actual social nets and welfare.
Can you seriously claim that Milei improved the material conditions of Argentinians? At best, he sold the country for a quick buck to make a few numbers look good, but ultimately doomed the country. I can't think of a single place where austerity was met with positive long-term outcomes.
According to this outlet [1], Argentina seems to have experienced a recent spike in homelessness.
As I said, it's foolish thinking you can fix everything with this "one simple trick". Housing is expensive because the market is gamed, deregulating it further won't fix shit. Those who make it expensive will always succeed in keeping it this way, if we don't take away their power and try to make the game fairer.
