This was prompted by the mooching and contributing thread. I think that's a little too simple given the debate, so I'd broaden it a little. How can you get money?
Contribute/sell something - free exchange of value
Steal - by force or not
Charity - asked for or not
Luck/gambling - I would include most "investing" in this category since you're often just hoping that the price will go up...
Any other big categories?
If I were to categorize into just two, instead of contributing/mooching I'd say asking/taking or perhaps free/coerced. For instance, is the government contributing or mooching with tax dollars? That can be a tough one but for sure it's collected through the threat of force.
