Libertarians and Republicans tell me that they don't need a labor union because they work harder, smarter, and faster than the others in their shop and the boss knows it. This only works until the Libertarian converts the rest of the shop to his philosophy. Then we have a race to the bottom.
How does this come about? Everyone trying to work faster than the next guy? The shop a contract to make so many units a month. which is being met without anyone working overtime. The boss goes to a variable piece rate based on the median production rate and the desired production. When the month's production is done the boss closes the shop until the next month - or lays off the slowest worker.
