There's a good deal of that. One hopes it would be less pronounced under socialism. But pay differentials are not the problem with capitalsim. Class differentials are the problem. Btw, I wasn't making productivity the key factor; it's a factor, but not the only one. Another consideration is providing incentives for people to go into kinds of work and areaswhere we want them. Thus we might pay a premium for people to become physicians in rural areas or inner cities. --jks
