Capitalism is fundamentally built on competition, it pits all participants against one another. It stratifies social bonds and breaks people apart because any cooperation represents unrealized exploitation.

Its why people are so miserable en masse, hostile, and chomping at the bit for targets to attack and hate. Its worse in America because theres almost no socialism at all to raise the floor of society - the country is buried in homeless and something like 1 in 5 persons is food insecure (probably higher now in the pandemic). If you fail in "winning" at capitalism to some degree you are supposed to feel fortunate shelters and soup kitchens exist. Sometimes. Society has broadly rejected them as the socialism they are and underfunds or destroys them where able.

Its also why drug addiction is totally out of control. Desperation and social isolation by our culture creates whole populations of people to be exploited by drug profiteers. Many other nations don't do this by catching people before they get that despondent or miserable and by helping (rehabilitation) rather than hurting (prosecution) those that get that bad.

The process is cyclic. The desperation feeds into the hate feeds into the predation feeds into the exploitation feeds into the desperation. But breaking out of it requires class consciousness that is opposed at every level - at the bottom by the animosity and inability to trust and at the top by the profits and power reaped through the harm done.
