I found this on a forum as I was looking up if there was a DIY
  solution to something: This answer, from "HoosierBuddy", is a
  perfect example of an jaded idealist who got "real-life" thrown
  at him more than once: "If this was viable, someone would hold
  the patent, someone else would have already offshored the
  production to China, the Chinese would have stolen the idea from
  that person, reverse engineered it, built a plant to make them
  by the millions, and you'd be able to buy them from Walmart,
  probably after being greeted at the door by the poor SOB that
  originally invented it and went bankrupt for his trouble!" It's
  a harsh response; and even he admitted he was low on caffeine
  when he wrote it. It doesn't mean you can't try your ideas out;
  but basically he's saying "Be careful if you decide to go 'ALL
  THE WAY'" with an idea, without looking first at what *might*
  happen if you don't plan ahead.
