Many of these hospitals were capitalist before the takeover too -- they just were beholden to local owners rather than big national firm owners.
Local ownership is a VERY powerful check on the power of capital. Communities can hold sway over owners beyond what is reflected the general ledger of the business. And one of the reasons big national brands are good at out-competing local business is precisely BECAUSE they can ignore these social costs -- even externalize them -- and reap further profit for the exercise.
Even if you're anticapitalist as fuck, this is why it is still important to buy and support local business whenever possible. Because the less local the business is, the less it cares about its customers and employees' welfare.
And when local owners get greedy and want to sell to big firms, it's very important to hit them with as much social punishment as possible. Friends don't let friends sell their businesses to hedge funds.
