Me saying the sky is green is a fairly straightforward concept, but it's still bullshit.

Using price as a way to efficiently allocate goods to those with the most need for those goods. All else being equal...

That's all well and good when you presuppose "all else being equal" and the people who need things are able to afford them, but that isn't the case at all. Instead we get what we have now, which is the "Haves vs the Have Nots." The rich have far more they need, and the rest don't get their fair share. Prices are raised because the rich can still afford it easily, and the poor can't afford not to pay outrageous prices for necessities.

There are more empty homes than homeless people, corporate landlords dominate the real estate market, the rich have multiple homes, and an entire generation has been priced out of home ownership.

Food deserts exist in poor neighborhoods and food costs are increasing at 3-4x the rate of inflation, while the rich eat lavishly and businesses spend millions on food and catering where half of it is thrown away.

The rich get elective medical procedures likes cosmetic surgeries for fun and are able to travel the word for experimental or questionably legal procedures, while insurance companies routinely deny care deemed necessary by doctors.
