Teaching Kids Computer Programming

There are a lot of calls from people leading tech companies to teach computer programming earlier in in schools. Well that is a great idea, there is a problem with implementing that. Computer programmer get paid way more than teachers. Why would a person who can program computers get a job as a teacher. How can this be addressed. I think tech companies should have programs where their programmers are send to schools to teach programming for a school year. This would provide a great source of talented and motivated people who have a solid understanding of programming to the school system. Just saying schools should tech programming without have a practical way to get teachers for that is not going to be successful. The tech industry should put it money where it mouth is.
