>The nicest houses I know are owned by traders who know how to use technical analysis.

If you have a large group of people who take risks while trading, and they form strategies indistinguishable from flipping a coin (like technical analysis), then at the end of the day you're going to have a lot of ex-traders who failed to make money and a few that look like rock stars - because taking large risks and being lucky is a "good" way to make money fast. It's the very definition of survivorship bias.
