You can burn cash in all sorts of ways. Take up a hobby. Develop a habit. Rescue too many pets. Have too many kids. While you cannot put any of the latter up for sale in the rotten kid auction, you can avoid losing money in the stock market.

The blame we like to direct toward “fat cat bankers” and rich CEOs notwithstanding, you can protect yourself from losses with hard work and, maybe more importantly, common sense. It also doesn't hurt to use readily available tools.
