While those can work well in some situations, I think one of the key problems is thinking in terms of whole ideologies. Capitalism has some good features and it's a great system if and only if its prerequisites are met. The same it true for every other system. Use capitalism (or variant) if a proper market exists. When a natural monopoly contraindicates market-dependent methods, use a cooperative or publicly managed service or whatever is more appropriate for that specific situation. A pragmatic approach should use all of the available tools. Pretending that one ideology is "better" without first considering the local context is the political equivalent of seeing every problem as a nail because you only use hammers. Replacing capitalism with another system that has a different set of problems isn't the solution. The core problem starts with the consolidation of power and resources, amplified by the unbounded risk created by rapidly increasing complexity. In software we (try to) manage complexity with various types of modularity. Separating the problem into manageable pieces limits risk and prevents some forms of common mode failure. Thus, a good "alternative to capitalism" is probably capitalism with a strict upper limit to the size of business and other organizations. if your business grows to more than N employees, it must be divided into pieces smaller than N.
