Big corps were hierarchical bureaucracies, but they were replaceable. Let's say that GM messed up, and didn't build cars that people wanted to buy. Well, you could buy a Ford or a Chrysler instead. You could even buy a VW or a Honda.
But if your central planning bureaucracy messes up, there's no way to bypass it to get what you want to buy.
Or was your point that workers' fulfillment is more important than consumers' satisfaction? That might be a workers' paradise, but it's a lot less nice for the consumers. But the problem is that workers and consumers are the same people. I'm not sure that it would be a net win...
Big corps are still hierarchical bureaucracies. They are replaceable in theory though not in practice. Funny that you mention car manufacturers which are consistently kept afloat by bailouts and subsidies in the current economy. VW can't go under, it would nosedive the economy of Germany and they would never let that happen. Workers without jobs aren't really good consumers.
Big corps get replaced all the time. It's a slow process, but it's effective. And even if they aren't replaced outright, the management can be replaced if the board so decides - the top layer is in fact "democratically managed" by their stakeholders, to the extent feasible. The problem is that even then they're still big, with no market discipline operating within.
