Who knows if a lot of people like him even live in America. I've met a few people here in Thailand that live a very nice life off RMT'ing in video games, always very interesting talking to them. I asked if they ever tried EQ though and they never heard of it lol. The amount they make off games is not good for America, but VERY good here. I live in the most expensive city in Thailand and the average person here only makes $600 a month and works their standard work week which is 72 hours (6 12-hour shifts). You could easily make $600 off playing EQ in a fraction of the amount of hours they would work doing a normal job. Hell, you could easily make $2000 a month and live a very nice life here renting a large house and going out drinking/partying every night (I rent a 2 story house in a private housing village with security guards and it's only $300 a month). You could live even better if you were doing it from a place like Vietnam. Imagine if you had started doing it during phinny, you would have sustained that income for the last 8 years.
Look at Aplus -- you could easily at least calculate his minimum amount of income simply by looking at his discord and doing basic math. He brings in at a minimum $15k USD per month and that's not counting plat + items sells + account sells. I imagine his operation brings in closer to $20k USD a month, and he probably lives in an area of China where you could easily live off less than $1k a month and be comfortable. So if you were to calculate for relativity just for the fun of it, he's bringing in the equivalent of making $80k a month in the US.
