Nathan Newman raises what I think is a weirdly neglected issue in the United States -- our artificially low supply of skilled professionals, particularly in the health services sector. Lots of qualified applicants can't get spots at nursing schools, medical schools, etc. simply because the number of places at these schools (or the number of schools) hasn't increased proportionately to growth in demand and the overall population. Training more doctors and nurses would hardly single-handedly solve the country's health care problems, but it would be helpful in implementing almost any approach one might care to try.
