With 1) you're comparing apples to oranges and you're still wrong. The turnaround in rail use in the UK began in the 1980s before the private train operating companies got involved. And if you're referring to the network itself being in "a decrepit state" before and now being improved to the point where it can sustain higher capacities ... well you can thank Network Rail for that (note: not a private company). The TOCs are headed for nationalisation anyway, leaving the ROSCOs as the big privatisation "success" (in that they've extracted enormous profits while not exactly contributing anything particularly novel).
What we saw with HS2 is a large (and frankly completely necessary) engineering project getting fucked around with and repeatedly chopped down until it no longer satisfied its original plan (providing greater capacity for both local and national services by providing a new North-South line that happened to be "high-speed") and became exactly what those wielding the axe that killed it accused it of ("just a way for some to get to London slightly faster").
