Since there have been some interesting comments on two separate posts from last week, I thought I would pull them together. To get up to speed, NPR ran a piece last week which decried (slight exaggeration) the low pay of doctors. I also commented on the failure of reporting on a minimum wage hike to note the extensive research showing that modest increases in the minimum wage (like the ones being debated) have no significant effect on employment.
The responses have raised issues about the appropriate wages for doctors and people who work at the type of jobs that get the minimum wage. The point that I wanted to make is that these two are linked. The wages of people working at low paying jobs are a cost to doctors, and doctors' pay is a cost to those earning low wages.
The logic of this is simple. While some wage increases may be absorbed in lower profits, and may also be offset by higher productivity, at least some part of any wage increase will be reflected in the prices of the goods or services that worker produces. This means that, other things equal, if we want minimum wage earners to get more money, then we want doctors to get less. Alternatively, if we join NPR in the drive to raise doctors' pay, then we want minimum wage workers to get less. This is basic economics/accounting; I doubt that any economist anywhere on the political spectrum would dispute this logic.
To me, the main economic story of the last 3 decades has been that those in high paying professions (e.g. doctors, lawyers, dentists, accountants, economists etc.) have managed to drive up their wages by sustaining and increasing barriers against competition (both foreign and domestic), while less-skilled workers, like autoworkers, textile workers, dishwashers, and custodians have been deliberately placed in direct competition with low-paid workers in the developing world.
The wages in these latter categories have generally been flat or declined over this period, while workers in most of the high-paid professions have seen substantial pay increases (e.g. the OECD reports that the real wages of doctors in the United States increased by 55 percent from 1964-1995 [sorry, it's not free data, so I can't link to it]). If this pattern is to be reversed, then the wage increases for workers at the middle and bottom will have to come at least partly at the expense of the real wages of high-end workers, just as the wage gains of high-end workers have come partly at the expense of those at the middle and bottom over the last three decades.
This is all accounting; one can debate the merits of specific policies to reverse the upward redistribution of income, but there really is not much room to debate the accounting. (My favored policy is free trade in professional services, so that doctors, lawyers, accountants and economists can enjoy international competition in the same way as autoworkers, textile workers and dishwashers, see chapter 1 of The Conservative Nanny State.)
