CMV: Pay rates should be based on productivity and quality of work as an incentive

I have worked in restaurants and customer service for twenty-something years. I have always held a work ethic based on selling my efforts for increases in pay; my reward for my labor. I have noticed a decline in this work ethic to the point where employees hold the position that rather than work for their pay, they should be paid and only then will they hold a work ethic described by diligence, thoroughness and quality of production. "I ain't doin shit till I get a raise!" -heard in every kitchen since somewhere in the late nineties.  I have seen over and over again slackers in kitchens demand raises with unfulfilled promises of exceeding effort always to backslide after a day or two to their normal attitude; proof that more money is not always an incentive or right for workers in lower level jobs.

I would say that market economics speaks against your idea.

If there are 50 places looking to hire diesel mechanics, and there are only 20 such mechanics available, then those workers are going to earn a fair amount and can demand more money because they are in high demand.

Same deal for plumbers. There are relatively few people who do plumbing work and when a person needs a plumber he or she is often willing to pay a premium price for such service due to the urgency of the work.
