You're the ignorant one if you picture China to be a bunch of people scavenging for food on the floor.
And if you're talking about one of the most underdeveloped countries in the world, chances are, they won't even accept the currency. You think a country like North Korea would recognize foreign currency? Chances are, they won't even have bank accounts to wire their PayPal money over.
If the country has both, a viable Internet connection that allows you to connect to UNITED STATES SERVERS without disconnecting all of the time and established banks, then the money earned from farming ONE ACCOUNT by HAND will not be enough.
You earn a maximum of 2k gold per hour. That's $1.60 per hour. Minus costs (electricity, computer hardware failures, playtime fees, bans), we'll say its $1.00 per hour. The person, non-stop, farms for 10 hours. That's $10 a day. You're saying $10 a day is enough to pay for necessities (and probably, feed a family) in a civilized nation?
Learn your shit before you speak.
