I guess there are ways in the real world that makes you earn a lot of money but that would surely be illegal and would put you in jail in no time. I think everybody would prefer to live with not so much money than to live with a lot of money but you can't spend a single dollar because you're behind bars.
Haha yeah they are day dreaming that earning money is easy or even doubling them. I think these people are those premature adult who doesnt really know what life is or just exploring the early responsibility in life. Others just want to trick or take advantage of other to make easy money in expense of their reputation. There is no safe way to double any amount of money without taking risk.
