Pyramid schemes usually don’t work well either, internet or otherwise. Occasionally they may bring in some income, but it often involves a lot of hard work, typically of questionable ethics — in other words, harassing a lot of people in different ways.

If it’s a business that could work well without the net, that’s a start — say, selling a certain specialty product. Think of the net as expanding your customer base. But be forewarned, there’s no “easy” way to make money, even online. If it seems too good to be true, it probably is.
