Do you have any actual criticisms of the policies he proposed?
> systemic student and other debt
The student debt problem is due to student loans not being dischargeable in bankrupty; this is certainly not something Hayek argued for.
>by monopolistic privatised healthcare
The cost of healthcare is to a significant degree driven by artificial limitations on the supply of doctors due to the government granting the AMA a monopoly on deciding who gets to be a doctor (and artificially limiting the number of medical places per year). This is also not something Hayek supported.
>fraud/boom/bust cycle that has replaced real game-changing technological progress
A lot of people would disagree that there has been less technological progress in the past decade or two than in earlier time periods. Even a decade ago, it was unthinkable that a machine could beat a human at Go.
> set out to destroy its really rather successful economic record of relative stability and prosperity.
The US experienced a higher rate of economic growth in the 1800s and early 1900s, before Keynesian policies were adopted, than it did afterwards.
