Strong claim. Bet it has more to do with trends like polarization or housing costs or something. Most corporations are providing absurdly cheap goods and decent jobs.
Corporations lobby/bribe politicians to implement laws and polities that negatively impact their constituents. The rest of the world has a single-payer healthcare system that is cheaper and better than what we have. Why? Because the healthcare industry has advertized and lobby'd for it to remain as it is.
Most corporations provide "decent jobs" to a limited subset of people. The vast majority of people are not making 100k/year.
