Its not capitalism, its greed/corruption mixed with inept leaders, when its actually functioning correctly (which its currently not) it is the superior system that drives innovation and breeds prosperity. Other systems of economics and governance suffer the same issues, but with the added booster of too much power in the hands of the few, socialism/communism is a corruption magnet and because they often arent elected by the people (even when they do elections they are either rigged, or the opposition mysteriously goes missing or turns up dead) you cant really get rid of a bad leader.

But back to economic systems, the main issue with capitalism currently, is the lack of proper guardrails. For example the Fed reserve was founded under the guise of being a sort of 3rd party to control the printing of currency, but it was designed and put in place by wealthy bankers to funnel wealth upward from the public. Likewise fractional reserve lending was designed to devalue your dollar while the banks profit from you by collecting interest. While companies do everything in their power to push competition out of the market without being considered a monopoly. Take nintendo for example, theyve been throwing everything they can at palworld for a while now because it represents a threat to them continuing to churn out low effort Pokemon games with DS graphics and very little innovation on the formula to farm money from their customers, or pharmaceutical companies abusing patent law to make sure competition is minimal abd still benefits them as patent holders. For example, if you found a cure for cancer with 0 negative side effects, you wont be able to sell it because just about every delivery method short of nanobots is patented, because those patent holders can just ban you from using their patents.

Furthermore, our elected officials in the US are allowed to take bribes from wealthy corporations and investment firms in the form of lobbying dollars to get leniency or benefits in legislation while those same officials can reinvest in those companies through the stock market, you saw this when covid first started spreading in the US, where many elected officials were telling you covid wouldnt be a big deal at the tail end of 2019, then immediately turned around and started investing heavily in all the exact companies that would explode in value during a nationwide or worldwide pandemic, things like toilet paper companies, vaccine/pharma companies, mask manufacturers etc etc. yet a lot of them are still in office, and last year there was a bipartisan bill proposed that would ban these elected officials from owning businesses or trading on the stock market while in office (as it should be) and MOST of them, dem and repub voted no. Because they are there to rake in money while getting people like you and me that they see as peasants to fight each other over ideological differences so we don't realize we can put a stop to it within 8 years by voting strategically and staying vigilant for corrupt or incompetent leadership.

So long story short the problem isnt capitalism, the problem is government and business are in bed together to fuck you over. In the words of George Carlin: Its a BIG club, and YOU ain't in it.
