Despite common misconceptions, capitalism has nothing to do with markets (let alone "free markets", which are a myth anyway). Markets existed thousands of years before capitalism did and exist in other economic systems.
No, capitalism is simply wealth extraction from workers to the capital owning class. Now we are saddled with all kinds of debt: mortgage, student loans, medical, credit card, car loan. Less than a century ago, houses were bought for cash, education was cheap or free and there was no such thing as health insurance.
We got all those things to keep us complaint worker bees and to squeeze every last dollar from our labor.
We've gone through 2-3 years of rapid inflation. A lot of things didn't get intrinsically more expensive. It was opportunistic ie greedflation. How did we tackle this? By raising interest rates. Again, that extract more wealth from labor. We could've dampened the economy with windfall profit corporate taxes instead.
Unfortunately this also completely rules US foreign policy too. Look at all the wars the US has started since WW2 and coups the US has backed. Look at how often that happens after said country actually (or even just threatened to) nationalized some industry. Cuba, Guaratamala, Venezuela to name a few.
It honestly boggles the mind how intentionally blind people are to this reality. Some see themselves as ultimately benefitting form this system by being capital owners. Very few will be. But others will never be yet defend this system instinctively anyway.
Oh for some class consciousness in the US.
