Capitalism provides the best incentive to produce goods and services needed by society. But unfettered capitalism concentrates wealth and power in the hands of to few. Trump's version of capitalism, unregulated and lightly taxed, while at the same time snipping away at the safety net for the poor and disenfranchised, is capitalism at it's worst. We need the built in incentives of capitalism, coupled with taxation to promote the common good like the infrastructure needed by a modern society. Without public investment our aging infrastructure will fall apart. Capitalism also needs strong regulation otherwise greed runs amok. If a venerable institution like Wells Fargo will stoop to fraud to increase profits, just how comfortable do you feel with the kind of self regulation that Trump promotes.

There are things in life that just aren't profitable but are necessary, that's where government comes in. There is no profit in cleaning up pollution. But it has to be done. There is lots of profit in cutting corners that result in pollution, so without regulation, corporations will pollute.
