No market-based solutions!
[WS:] The problem with market-based solutions is that they operate in the same way as "socialism" did in x-USSR - as cover up for practices being its own anti-thesis. Likewise, market-based solutions are proposed to cover up monopolistic practices of corporations.
But other than that, markets can be very valuable for sending and receiving information about values and preferences - something similar to what opinion polls do today, only better. Markets can also be very valuable for behavior modification - again something similar to what law enforcement does today, only better.
In short, markets can be very valuable if used as one of the tools of government planning. They become a disaster only when they are used as ideological cover up for the absence of such planning.
