I've made this point at various times over the years, but it is appropriate here: corporations are a creation of government and can therefore be regulated in virtually any way one wants. Obviously (I think), that doesn't mean that one can simply appropriate their assets without compensation, but it does mean that limitations can be placed on organizational structure and compensation schemes. A percentage of worker ownership, or limitation on executive pay, for example, are entirely legal and reasonable. They are, literally, the cost of doing business (as a corporation).
