80% of employees say their workplace is toxic

The fundamental relationship of capitalism, i.e. capital owner employing people to work for him and make him money, is quite toxic. No wonder it seeps into the workplace relationships.

This is exactly right and people want to ignore the fact that unless you play the capitalism game, you basically die.

There are no alternatives

Yep. Toxicity is just built in into foundations of our society and, like you said, at this point there are no alternatives.

Capitalism is based largely on coercion. The overwhelming majority of people would not be doing what they do most of the time if their needs were already met.

Probably built into the foundations of life.

Hunter-gatherer tribes have healthier dynamics than settled neolithic societies ( like ours).

What does that mean, "healthier dynamics"?

All life is a strife for resources. Strife is conflict.

The important question is where you draw the boundary line for the conflict. These groups are fighting together against the environment, whereas we are both fighting the environment and against each other (in capitalist system, everyone is competing with everyone else all the time). Hunter-gatherer tribes basically implement some form of socialism, with little to no private property and cooperation instead of competition.
