In one sense you are correct. But do we really need so many people doing what is essentially journeyman work, building trivial one-feature products with piles of VC funding that forces them to produce things that make money, rather than things that are good or do any any good? There are a lot of deserving open source projects that you can practice on, rather than stumbling around trying to figure out what you want to do while looking for an exit to justify your latest round of funding.
