Decades ago, an old friend of mine had a go-getter son, who started a lawn care business when he was ~15. Son was talented, and his business grew very fast. (This was in a well-to-do suburb, before there were so many lawn care businesses. Plenty of good HS students available to hire, and the trucks were leased.)
For getting into top-ranked colleges, "the summer business I started in HS is already paying me more than your median graduate's full-time job" is a slam-dunk argument.
