I would recommend David Graeber or however it's spelled writing. Any time you read anyone's opinion take it with a grain of salt but Debt and Bullshit Jobs address many things, some of which can be taken as criticism of capitalism.

James C Scott is another anthropolgist and his most accessible book is probably seeing like a state. It's relatively even handed in it's critques of capitalism as it focuses on states including the USSR. It highlights quite well how markets and states can crush humanity because they have wildly different goals to people.

You probably don't want to jump right into hardcore theory so this might be a gentler intro into asking why society is the way it is and how it might be different without expressly pushing a particular political theory.

Capitalist critiques mainly.
