We have enough production in some areas — but not in others. Some goods are currently overly expensive because the inputs are expensive — mostly because we’re not producing enough. In many cases that’s due to insufficient competition. And there are some significant entrenched interests trying to keep things that way (lower production == lower competition == higher prices).

And FWIW, the US’s current “tariff everything and everybody” approach is going to make this much, much, much worse.

I am certainly not the friend of billionaires. I’m perfectly fine with a wealth tax to fund public works and services. All I’m against is overly simplistic solutions which just exacerbate existing problems.
