The Problem With the Socialist Economy

If we turned it into a socialist economy and we just had a government entity take over all the capital, we can keep everything as it is. But instead of all of us working for the 10 fat cat capitalists that own the entire country, we now work for the one fat cat government that owns everything. And then nothing changes, right? In fact, because it's the government is the government is made out of angels as opposed to evil capitalists - this means better economic allocation. This completely ignores the idea of entrepreneurship, which is something that not only the socialists don't get, but it's also, you know, in mainstream economists don't have any conception of Entrepreneurship.
