What's right with economics would have produced a shorter thread
Here are some issues I have with economics:
The idea that it is a science, or that there is an objective truth that economics can find. As Butchers and VP have said, economics is an ideology, one that exists to support capitalism and the ruling class.
The blind faith to their two main a priori ideals - the perfectly rational human, and the idea of perfect markets. This is particularly galling as it's often touted by the same people who reckon economics is an objective scientific enterprise, but once faced with empirical evidence that their a priori beliefs are wrong they won't alter their beliefs, instead denying the evidence that is available.
Tied in with this is a complete (wilfull) ignorance of power relationships, as demonstrated by the person on this thread claiming employment relationships are voluntary.
Also tied in with it is the idea that competition works and always leads to a better outcome for individuals, a denial of cartelisation and monopolisation even though these are the most profitable states for companies to exist in.
I particularly hate the idea that people always make rational utility maximising choices and so therefore all voluntary transactions maximise utility for all actors involved and that therefore all we need to do to make the world amazing is to have more and more voluntary transactions. Feeds into liberal ideas of primacy of the individual and fails to take account of structural issues.
Oh yeah, the idea that private sector/public sector are actually separate entities, or that economies can't function if public sector is >50% GDP
Fuck loads that is wrong basically, very little that is right.
