Following on from MW's piece below, I'd like to postulate two new laws. For which I expect to receive the Noble Prize for Economics.
1) What is morally correct is economically efficient.
following on from this
2) The sum of all good State regulation raises aggregate land rents. The sum of all bad State regulation reduces them
By the "State" I mean all of us acting under agreed laws and social norms.
If 1 & 2 are true, there are many instances of policies espoused by economists and the main political parties that run contrary to this.
