Got idea liao.

One way to get rich is to start those "trade your way to riches" and "get rich through ebay" seminars, and target those stupid and naive engineers who think there really are such simple and risk-free short-cuts to get rich.

Sell them a dream and you get rich yourself while they continue to 'spend lots of time and thousands of dollars to attend "trade your way to riches" and "get rich through ebay" seminars'.
