All you have to do is look at California, which is hemorrhaging its middle class, but California doesn't care sadly. The only thing California cares about is more silicon valley startups...
It is only a matter of time before most of the technology firms (including those based in the Silicon Valley) move to some tax-friendly state, such as Nevada or Utah. Who knows, even the Hollywood sector might follow suit. After that, California with all its illegal aliens and refugee cities will be a third world ghetto, if it isn't one right now.
For some strange reason these firms tend to be very liberal. I agree that technology firms will eventually move to more tax friendly states, but this will not happen before shareholders force this to happen by putting pressure on managers of the tech firms.
