Yep, communism isn’t state-owned means of production as this post implied, it’s democratic - that’s one of the reasons the USSR model failed.
Inventors in the USSR were paid just as well, if not better than, their American counterparts. Mind you, this is not a defense of the USSR or authoritarian communism, Stalinism killed many people. However, maybe educate yourself on how these systems worked before critiquing them. A critique of communism does not negate critiques of capitalism.
Also - be careful with conflating inventors and capitalists. Inventors are often laborers who have their work profiteered by from the owning class - famously, Nikola Tesla lost control of his patent for DC motors and was left penniless as capitalists formed a new utility company.
In 2018, 11.1% of American households were food insecure. While this is better than many developing and historically colonized countries, this statistic is still worse than for many other developed nations.
Health care in the US is so expensive because there is currently a capitalistic private ownership of insurance because historic efforts for socialized medicine were crushed by the ruling class. Additionally, efforts to implement socialized programs have been systematically handicapped by private insurance company stakeholders.
In Finland, a country with socialized education, tertiary education is free to citizens. In the US, the average cost of attendance to a public university, the cheapest category of 4-year tertiary institution, is $26,000.
Housing prices are skyrocketing because private equity groups and hedge funds are rapidly buying property to drive up prices for profit.
You are pointing out problems that capitalism and free markets have given us, and pointing the finger at socialism, when efforts to socialize each of these necessities have been systematically squashed. You are contributing to misinformation by writing this post. Please do some research and back up your claims with reliable sources before spouting nonsense you don’t understand on the internet.
