why was william graham sumner demanding for government involvement in business?

Answer 1

I can see no demand by Sumner for government involvement. Quite the contrary, Sumner's popular essays gave him a wide audience for his laissez-faire advocacy of free markets, anti-imperialism, and the gold standard. Sumner's work with folkways led him to conclude that attempts at government-mandated reform were useless. Sumner was active in the intellectual promotion of free-trade and he heavily criticized socialism/communism.

Answer 2

he's a communist, like the rest of the democrats.
