Labor is an economic input, not terribly different from raw materials or other commodities. Labor has an economic value, and that value is generally based upon the productivity of the worker. Building upon this concept, we can observe that younger workers with little or no work experience are generally less productive than older workers - and looking at the wages people earn at various stages of life would support this.
What happens when you set an artificial price on a product? You are either going to create a surplus or a shortage of that product. Pick anything. Mustard. For the purpose of this exercise let's say the free market price of 12oz of mustard is $2.47. Let's set an artificial price on mustard and think about what happens economically:
- Mustard set at $6.00USD per 12oz bottle: At $6 a bottle there are going to be fewer consumers willing to buy. Buyers will turn to alternatives, or simply forego buying mustard since they can use the same money more efficiently to meet other needs. End result - a mustard surplus, as producers sit on top of large quantities of unsold mustard.
Mustard set at $1.00USD per 12oz bottle: At $1 a bottle more consumers are willing to buy. This will include new consumers who previously could not afford mustard, and buyers who will find mustard a viable alternative to other condiments that cost more. As there is considerably more demand for $1 bottles of mustard than there is at higher price points, this low-priced mustard will fly off the shelves. End result - a mustard shortage, as producers are unable to keep up with the demand that exists for $1 bottles of mustard..
- Minimum Wage set at $7.25USD per hour: At $7.25 per hour laborers who don't provide at least the same amount in productivity for their employers are priced out of the job market. Likewise, jobs that require less than $7.25 worth of productivity to accomplish are eliminated from the job market. End result - a surplus of workers whose productivity is less than $7.25 per hour. This surplus of workers is represented by unemployment..
Minimum Wage set at $15.00USD per hour: At $15 per hour laborers who don't provide at least the same amount in productivity for their employers are priced out of the job market. Likewise, jobs that require less than $15 worth of productivity to accomplish are eliminated from the job market. End result - a surplus of workers whose productivity is less than $15 per hour. This surplus of workers is represented by unemployment.
Minimum Wage, Who Gets Hurt? Low-productivity workers get hurt, as a rising wage floor prices them out of the job market. They become "surplus labor", aka unemployed. Who are low-productivity workers? The young (only 3% of people above the age of 24 work for minimum wage) are disproportionately impacted. By pricing the young out of the labor market early in their lives, their chances at earning higher wages in the future is also negatively impacted.
Minimum wage hurts the young.
