This is not to say that in this respect all is for the best in our present world, or has been so in the most liberal past, and that there is not much that could be done to improve the opportunities of choice open to the people. Here as elsewhere the state can do a great deal to help the spreading of knowledge and information and to assist mobility. But the point is that the kind of state action which really would increase opportunity is almost precisely the opposite of the “planning” which is now generally advocated and practiced.
Reminder: no one in any serious position is advocating for central planning. This is the myth that the modern Republican party has centered itself into fighting against.
