The "capitalist" economies are constituted by economic planning as much as the "socialist" ones. The issue with planning of any kind is that it requires political freedom, including, crucially, freedom of speech, to ensure accurate information from which to plan, and accurate feedback as to the results of plans. In the capitalist countries, the vast majority of information that must be known to plan the economy is proprietary, ie, secret as far as the public is concerned. And the institutions which are most concerned with planning are banks. In theory banks are supposed to finance the capital development of the economy. They mostly do and it is this function which constitutes most of the ground-level economic planning in capitalist countries, as bankers are basically (again, in theory) engaged in a constant exercise of reading the future to determine where to put money most profitably. The finance bubble in the 2000s could be seen as a failure of planning in this respect. The ability of the planners (banks) to gather and respond to accurate information and feedback was crippled by the fact that the people running the banks were criminals.
