Peter explains, in a very easy to understand way, why minimum wage laws hurt unskilled workers: Where Have All the Gas Pumpers Gone?
Before bringing on another worker, an employer must be convinced that the added productivity will exceed the added cost (this includes not just wages, but all payroll taxes and other benefits.) So if an unskilled worker is capable of delivering only $6 per hour of increased productivity, such an individual is legally unemployable with a minimum wage of $7.25 per hour.
Low-skilled workers must compete for employers’ dollars with both skilled workers and capital. For example, if a skilled worker can do a job for $14 per hour that two unskilled workers can do for $6.50 per hour each, then it makes economic sense for the employer to go with the unskilled labor. Increase the minimum wage to $7.25 per hour and the unskilled workers are priced out of their jobs. This dynamic is precisely why labor unions are such big supporters of minimum wage laws. Even though none of their members earn the minimum wage, the law helps protect their members from having to compete with lower-skilled workers.
Employers also have the choice of whether to employ people or machines. For example, an employer can hire a receptionist or invest in an automated answering system. The next time you are screaming obscenities into the phone as you try to have a conversation with a computer, you know what to blame for your frustration.
…
As a result, many low-skilled jobs that used to be the first rung on the employment ladder have been priced out of the market. Can you remember the last time an usher showed you to your seat in a dark movie theater? When was the last time someone other than the cashier not only bagged your groceries, but also loaded them into your car? By the way, it won’t be long before the cashiers themselves are priced out of the market, replaced by automated scanners, leaving you to bag your purchases with no help whatsoever.
