A few questions about what does or does not constitute gambling. I don't think the moral judgments about gambling matter here, since we're just looking at the definition.
Is there a difference between gambling and investing? To me, the major difference is that investing in a company actually means buying a share of the business, and is necessary to getting a new business of the ground. But you can have a boxing match or a ball game without betting on it, and the gambler doesn't share in the revenues from tickets, etc. Nor does he share the possibility of owning an ongoing money-making concern, or create jobs.
In, say, an office football pool, you "invest" in order to win the pot. However, no wealth is created; just transferred.
Does casino gambling gets a little closer to investment, or is it just another transfer of wealth?
Wrong time of year for this one, but the soldiers who cast lots for Christ's garments are often said to have been "gambling at the foot of the cross." I'm not so sure that's gambling, though. No one stood to lose anything. They were just choosing one member of the group at random to get a windfall. Is that gambling?
