If you compared the total amount of money spent in the US on tennis where the parents are planning/hoping for a tennis scholarship to the total amount of money/value awarded to US kids for tennis scholarships does anyone think it would be even close? Over the years I have seen a lot of money spent and very little money received.
Tennis for juniors cannot be about college scholarships. If it is purely financial return you are looking for tennis does not make the cut.
That being said I think tennis is a great opportunity for many reasons.
