The “Living Wage” thread has made me ponder the question, of to what extent a prosperous society (such as the modern U.S.) benefits, as a whole, from trading economic efficiency for compassion for the least fortunate. Being kind of a numbers nerd, I’d like to present the question as a mathematical abstraction, so please bear with me.
I’ll start with the assumption (unproven, of course, and most certainly an overgeneralization) that every regulation or law that results in a redistribution of wealth also causes the market to work inefficiently, and reduces the overall wealth of the society. (In a nutshell, it’s the argument that at some point, increasingly-progressive tax rates disincentivize the top earners from starting businesses, hiring workers, etc., and as a result the whole economy suffers.)
To model this, I’m going to assign “prosperity units” to countries, which are NOT a zero-sum game. If the United States currently has 100 prosperity units, then Somalia might have 8. Think of them as representing, in a very general way, the (mostly material) quality of life in a country.
Those prosperity units are then divided amongst the quintiles of the population. A country like Saudi Arabia (one with a super-rich ruling class and a huge mass of poor people) might have 60 total prosperity units, divided 48, 3, 3, 3, 3 among the quintiles of their people.
Now imagine a fictional U.S.-like country with a distribution of 50, 30, 12, 5, 3. That is, the top 20% of the people (in terms of wealth) have a “prosperity” of 50, the next 20% have 30, etc. Using this example and the previous one, 80% of the people in this country live better than all but the top 20% of those in the Saudi Arabia-like one.
If the country were to implement economic and tax policies that distributed wealth evenly among all quintiles, I think you would certainly NOT end up with 20-20-20-20-20. The market distortions and disincentives would, I think, badly effect the markets and economy of the country, and you’d end up instead reaching an equilibrium more like 10-10-10-10-10. Communism has largely failed for a reason, after all.
But, let’s say that, looking at the specific numbers, if you’re over a 45, you live like a current-day multi-millionaire. 31-40 is upper class, but you still have to go to work. 21-30 is ‘normal’ upper middle class. A 10-20 is the range of middle class. 5 or lower is poverty-level; you’re not starving, but you barely live paycheck to paycheck, and if not for social programs, you’d be living out of your car.
Sorry for all the preamble! The debate is: take our vaguely U.S.-ish country of 50, 30, 12, 5, 3. Imagine a proposal of economic and tax reforms that would raise the lowest out of poverty, but shave off 10% of the nation’s total prosperity. (That is, the resulting wave of business-owners moving out of the country, some poor people working less hard because the safety-net is bolstered, etc. has been baked into the numbers, and the new equilibrium has removed a whopping 10% of the country’s wealth and productivity.) The resulting 90 prosperity units end up being 38, 24, 12, 10, 6. 40% of your population is now raised from poverty, their economic well-being in some sense doubled. 40% of the population has taken (on average) quite a hit. The 20% in the middle are still mostly lower-middle class.
Would that change be for the overall betterment of the country? Would you press the magic button that would effect this change?
A more abstract way of thinking about this: I think most Dopers would agree that a 500-2-2-2-2 country is not as desirable as an 50-40-30-20-10 one, even though the overall productivity and wealth is much lower. I think most Dopers would also agree that a 50-40-30-20-10 country is more desirable than a 15-15-15-15-15 country, even though the latter is more equitable, and the poorest are better off.
Where do we draw the line, when deciding as a country how much to trade away wealth/productivity/efficiency for compassion?
And before you say it: yes, I realize that was all needlessly complicated.
