Totally for high speed rail depending on if the money gets to it. Japan has shown a private/public transportation system is possible. That being said, it'll probably go to a politicians friend's company and it'll end up like the $90 billion California train.
The current K-12 public school system is a joke, lets fix that first. I'd rather see school of choice. You can already qualify for preschool if you need it. For college, let's lower tuition before making the tax payer pay off the current tuition debt and then paying for free college for even more. (but really lets not pay people's debt)
