In a free market if you earn only $30 dollar a month its because your worth $30 a month. You are literally fucking useless and what you can do is so useless that someone will only pay you $30, wow. Find a way to be more useful or STFU.
Know why people earn more than you? Because what they do is more useful and more valuable.
Want more money? DO SOMETHING MORE USEFUL! BECOME MORE SKILLED! or stfu.
You know things aren't that linear! If a corporate can threat the region with unemployment they will exploit the locals as far as they can. Even if what they do worth millions they will always try to pay for the lowest bid.
I see many uneducated good for nothing being well paid at Europe, and many skilled workers at Asia being overexploited.
Free market? Then you agreed to work for $30 a month.
Non free market? Then its socialism/communism/fascism and your just an animal being farmed by your government.
In a free market you agreed to work for $30 because your worth $30.
More uneducated good for nothing in the EU? EU is not a free market, it is socialist as fuck.
Many in Asia exploited? Where? China? Communist, not free market.
