Capitalism is the giant monster that we bring out of a box when we want to win a war, and have a hard time getting back into the box when the war is won. A well-informed, vigilant public keeps the monster in check, and a poorly-informed, lazy public lets the monster run wild (meanwhile, Socialism is letting a giant...golden retriever out of a box?). Note there are many signs lately that Capitalism can/will create climate-change tech (and quickly), since there is money to be made in electric cars, solar, wind, veggie-burgers, etc. Could Socialism do that so quickly? I don't think so...we would all be mired in committee meetings while the Earth burned up...
