The question you asked, slightly rephrased: "What is the most efficient way to earn money without spending money?"

Sorry kid, but this is capitalism. You've got to spend money to make money - everyone knows that. The only alternative is wage-slavery. Not very appealing, I know.

It's kind of like gravity. The bigger your pile of money, the more money your pile will attract.

The smaller your pile of money, the more likely some or all your money will be siphoned off by the gravity created by the mass of some other guy's fortune.

No, it's not fair, but that's life in capitalism. If you don't like it, you should consider preaching anti-capitalism.

Now if you'll excuse me, I have to get back to browsing for multimillion dollar condos in Manhattan.
