For the first time I can remember, I disagree with Dr. Sowell! Perhaps a pay increase is a good idea, but just putting the money out there is not the way to do it.
How about, instead, paying for performance: continue paying their regular rate, but give them a bonus (divided by committee) for decreasing government expenditures with no corresponding reduction in service to the general welfare? Say, 5% or 10% of the total reduction spread over 5 years? We already have a program like that in place for government employees and military members, but with the bureaucratic spend-it-all budget mentality, these decreases rarely happen. Incentivizing elected officials to put the government on a diet would invert the current bloat-rewarding system.
