I mean, it's hard to argue against that, because there is evidence that it works in Europe. Might need less corrupt governments in some places tho

Really depends on what you mean by market. Like a market has existed since humans have and probably will until post-scarcity. The market we have now with arcane rules that all end up enriching people with more money than any one human will ever need is something that has been in the making since industrialization. That market is pretty much at a point where salvaging it is not really possible even if there was any attempt made to do so. Control of how that market works seems to be at the hands of bad actors who just want to squeeze as much wealth out of it as they can, screwing over anyone else.

Like for example the power companies in my country stopped producing power on their own and bought power from neighboring countries just to sell it to locals at a higher rate. Basically just acting as middle men without providing anything of worth. That drove the price of power to hit 300% more than the year prior. The only reason they stopped was because our government started their own power plan with locally produced power forcing those companies to compete with it but the damage was done and power prices never went back to normal like they never do when companies inflate prices. A market regulated by people who only care about profit will never work.

That's an extremely narrow view point I'd say. In my country the government promotes the growth of existing big corporations so that there can be more jobs and infrastructure development - but this has in the end lead to a widening of gap and has essentially only made the rich even richer.

I genuinely believe promoting start ups is better for the middle class than big corporations, as usually startups pay a crazy amount of money if you ask for it compared to what a big rich corpo would give you (ironically).
