Answer:
I would say Capitalism
Step-by-step explanation:
Because, that's literally the definition of Capitalism. I can also tell you from first hand experience of living in a capitalistic society, that that's what it is.
Capitalism is basically when individual people have the majority of control over starting and operating their own business without government intervention (as long as said business doesn't break any laws or anything, then the government won't/can't get involved).
Hope this helps :)
