History help!! Which belief was held by most Progressives?
It depends on which country and which period, and therefore which progressives we are talking about. To give you an idea: In the European enlightenment & its spinoff in the original USA constitution, then (A). In the USA in the 1920s – 30s depression, the massive agricultural subsidies the Democrats gave would make it (C). In the Western world today, probably (D). In the British 19thC, J. S. Mill, a progressive of the Left if there ever was one, argued strongly for (B) – education too, he said, should be privately provided for. I don’t know who asked you this stupid question, but you can tell him from me to define his terms better next time.
