Baking a cake, an economic analogy
If you bake a cake for 30 minutes at 350 degrees, you'll get cake. If you bake for 35 minutes at 325 degrees you'll get cake. So there is a range of temperatures that will work for baking. However, the range of temperatures that will work is limited. If you bake the cake at 500 degrees you will get something that is burned on the outside and raw in the middle. Likewise, if you attempt to bake the cake at 70 degrees, the mix will spoil rather than bake. And this is a good analogy for the free market's role in society.
Too little of free market forces, socialism, is like trying to bake without enough heat. There is not enough incentive for labor and the economy stagnates. Liberty fails as public unhappiness grows.
Too much unbridled capitalism is like trying to bake a cake at 500 degrees. Money migrates to a few in excessive amount (the overcooked crust) leaving the mass in the center poor and raw. This leads to instability. Eventually, the only way keep order is to restrict the liberties of an increasing large number of unhappy people.
Right now the Republicans are trying to turn the oven way too high.
