• Investors generally fare better in index mutual funds and exchange-traded funds versus their actively managed counterparts.
• The average investor pays about five times more to own an active fund relative to an index fund. This makes it tougher for active funds to outperform index funds, after fees.
• However, the lowest-cost active funds tend to beat the average index fund in categories like junk bonds, foreign stock and global real estate.

If you’re in a dry, hot environment and evaporate water in a swamp cooler, you lose about 2.3MJ/l (0.6kWh/l), from which you can skim maybe ~10% (0.06kWh/l) with a thermocouple. If you’re charging a Dacia Spring consuming 156Wh/km, you’d have to evaporate ~300 liters of water to drive 100km. (Edit: some errors.)

But then, what if you bought solar panels and a wind turbine instead of thermocouples and water?

That pattern is strong in the sick sad history of computer-aided collaboration. The real geniuses were sidelined and kept poor.
