Mike Munger, speaking of my own modest trolling efforts, suggests it might be. This is a link to a paper of his on Euvoluntary Exchange & the Rawlsian Difference Principle regarding which the following points suggest themselves
Munger isn't going for the low hanging fruit here- the most obvious one being
1) the argument from price/service provision discrimination w.r.t. Goods and Services which are either natural Monopolies/ Monopsonies or else Legally constituted as such. For e.g. the State may choose to define itself as having the monopoly of legitimate coercion.
In this case, Economics 101 (which Rawls assumes we have access to 'behind the veil of ignorance')
says that there will always be some goods and services such that price/ service provision discrimination will be both allocatively and Hicks/Kaldor efficient- i.e. yield higher output and potentially help the worst off for e.g. by the Monopolist distributing a small percentage of profits to the least well off One percent or half percent or setting up a hospice for lepers or something like that.
However, segmenting the market on the basis of things like ethnicity, gender, inherited status, having a PhD, etc may be the cheapest and most effective way of preventing 'leakages'. Thus, the Difference Principle might endorse Racism, Sexism, Credentialism etc.
More generally, by giving rich and powerful people preferential treatment, a Justice or Political System gives them an incentive to support the system rather than 'Hirschman Exit' or form a close dealing coalition designed to circumvent the System in question.
Munger does, however, point out that paternalistic Legislation which assumes that poorer, less educated, or lower bargaining power people can't be trusted to make fair bargains, may in fact end up hurting them.
Indeed, we would expect that either there will be 'Agency Capture' or some 'Goodhart's law' type perverse effect, or else a class of intermediaries will arise to circumvent the Govt's interessement mechanism.
(I may mention, that a Binmore type (i.e. with no external coercion) 'repeated game' approach comes unstuck for a similar reason because there is no way of distinguishing phenotypal 'canalisation' (which is in the core) from 'capacitance diversity' (which may not be and has high hysteresis and is associated with things like ressentiment and moral panics) within the Evolutionary Stable Strategy. What I mean is that a speciation type event occurs such that the co-operative representation of the underlying strategic game has a splintered grand coalition)
2) Munger is sticking with the notion that profit needs to be positive to motivate entrepreneurship and Capital formation. Actually, it can be negative because
a) Non-monetary returns - e.g. learning, status, and network effects
b) Precautionary Asset diversification and Strategic behavior.
c) Global contraction and negative Expected real interest rates. Here, people's need for diversified precautionary balances means that there is still an arbitrage opportunity.
One important point, generally overlooked in this context, is that Human beings have always had an incentive to practice charity because producing more than you need is a good hedge against lean years. This holds even if there are no 'reputation effects' or 'moral economy' type vesting of conditional Entitlements.
Portfolio Choice theory explains why an Entrepreneur who will never make a profit may yet gain wealth, status- even a seat in the House of Lords, like my old mess-mate, Karan Billimoria- without attracting the ire of his investors. On the contrary, the fact that they backed a 'neverwozzer' (Silly Billimoria chose a name for his beer that barred him from America) shows their methodology was correct.
My point is that the information processing function fulfilled by the Entrepreneur continues to attract a return even if Profits are negative. (I should explain, Economists define Income as what you can spend without diminishing your Wealth. In this case, Capital (broadly defined) is having to donate a portion of its depreciation to the Entrepreneur simply so as to continue to exist at all)
Human Societies have evolved to cope both with Expansionary and Contractionary phases. In a perpetual steady state, Munger's objection to tinkering with the outcome of a Rawlsian mechanism- viz. that this amounts to violating the veil of ignorance condition, seems merely scholastic. However, this ceases to be the case once we acknowledge the reality of the coexistence (or indeed co-evolution) of Entrepreneurship with 'Negative Profits'. Capitalism is not a vampire. It is a wounded beast which dies to keep Entrepreneurship alive. The troll outlives the blog.
Certainly, the opposite may happen. The feudal lord may treat the Merchant as a fatted calf. But Entrepreneurship is the troll lurking under the bridge over which all the King's horses and all the King's men pass over to oblivion. In India and China, comprador Merchants, in league with the Evil East India Company (vide Pirates of the Caribbean) ultimately killed off the feudal lords only to be betrayed by their descendants, like Jappa Pallikathayil or Nina Burdwan, who studied Political Philosophy, and began jabbering about 'fairness' and 'exploitation' and other such nonsense. Which is why trolling bleeding heart blogs is actually euvoluntary.
