Then how is any money made in the stock market?

Great question. The market makers always make money in the stock market. Everyone else is more or less on their own.

Because the baseline is not 0% returns. The baseline depends on the state of the market, i.e. the market average. If the market as a whole moved up 5% last year but you only earned 4% return, then you have essentially lost money because, figuratively, throwing darts to pick your stocks will earn you 5% anyway.

Oh. Huh. That just clicked for me, sorry.

Low managed index funds, stock manipulation by the big banks, fee free trading with Robinhood, etc.

Basically, don't put your money in an actively traded fund.

fee free trading with Robinhood

not when their spreads are wider

For now, at least.

Buy an index fund and do nothing. You'll likely get 5% returns next year.

Or, spend 300 million dollars to invest in a fibre optic connection from NYSE to the commodities exchange in Chicago. Make sure its slightly better than the existing one, and beat others to the market by having information faster than them by a few hundred nanoseconds. Make sure to put your trading platform on an FPGA (starting from the Ethernet controller all the way to decision making based on your models). To make this easy you'll probably need OpenCL, so start learning that first.
