Review the history of U.S. minimum wage. Minimum wage has been something advocated by labor unions. Why do labor unions advocate for minimum wage? Labor unions advocate for minimum wage so their skilled workers will earn a pay increase every time minimum wage is increased. Increase minimum wage by 100% to $30,000/ hr. then skilled labor like airline pilots, electricians, jet engine mechanics, law enforcement, plumbers, registered nurses and school teachers will demand far more than $30 per hour.
For over 100 years, U.S. corporations have moved jobs outside of U.S. border. If minimum wage doubled, would more or less jobs be sent overseas?
There are robot/technology substitutes for labor. Often the cost of robot/technology makes replacement of labor impractical. Raising minimum wage makes robot/technology more attractive for corporations.
What would prohibit landlords from doubling rent? Some landlords may not want to double rent, but labor costs for landlords would force significant increase in rent.
There will be a day, I am sure, about 25 years from now, minimum wage in U.S. will be about $30/hour. Now? Today? Bad idea.
