There are other places than just the stock market or the gambling table one can make money. For example, one can have a welding skill, buy a welder for $500 and then complete a job for $1500 making a $1000 profit. Or one can buy $500 of building material and build a deck for someone at $1500 and profit $1000. One can buy $200 of plumbing supplies and build and install a central distribution manifold and make $2100 clearing $1900 in profit.
As I said, the market is not the only place one can make money.
