Here’s a resource yah can use to start the education towards knowing economy. https://www.youtube.com/channel/UCVBfIU1_zO-P_R9keEGdDHQ
Otherwise, I generally recommend reading Smith, then Ricardo then Marx in that order when learning about Economy and Political Economy. Those three share a lot in common, but one after the other expands and adds ideas the other hadn’t from their predeccesor. I consider Cockshott over Harvey because Cockshott can back up his claims empirically and rationally, Harvey on a lesser level.
