There is a difference between the two.

With communism, government owns all of the capital outright. There is no private ownership of business or industry. Communism always collapses very quickly because there are no market prices.

With government being the only owner of capital, you can't have a market. It takes (at least) two property owners to tango and to generate market prices. Without market prices, you can't have profits and losses. So the government has no idea what they are doing. They don't know where to add resources, and where to take them away.

No market signals.

Poverty and starvation comes quickly with communism.

"The powers that shouldn't be" use communism more as a weapon to destroy a targeted society, than as an actual economic system. Communism is a tool to destroy…and then it's replaced with something that has at least a hint of rationality to it.

Fascism is usually the go-to for "the powers that shouldn't be" because there's a hint of rationality that keeps it from dying quickly. With fascism, government and corporations are "separate," but act as one. As opposed to communism, government isn't the sole owner of capital.

Markets still exist … profits and losses exist … But the whole process is warped and retarded.

Corporations tied to government are kept in business when they should go bankrupt. Resources that should be freed to do more productive things, are instead kept in losing ventures.

With fascism, THE BIG decisions and investments are made, not for the consumers, but for the power of the government. The corporations are arms of the state.

Government won't censor you, the corporation will, on behalf of the government. Government won't counterfeit money; the private bank will, on behalf of the government.
