I'm all for everyone making $15/hour baseline
Don't worry, your government is busy inflating the currency quickly enough that that will soon be worth less than what minimum wage is now (counts bitcoins).

Congratulations, you just became too expensive and your job has been sent overseas/your company went bust/You got bought out in an aggressive merger and everyone in the company got laid off.
