I think that you are wrong in many ways, but I will point out just one of them: GPS was developed in the 1970s, and was made available for public use in the early 1990s. Quite a lot of people whose taxes paid for the development of GPS in the 70s were still alive in the 90s to make use of it. In fact, many of them are still alive today, 30 years later. They have benefited greatly from that investment.
