Nonsense
You spout absolute drivel.
Since I actually live in a country with HSR and use it weekly, I am far more informed than you about the costs. You can go to other countries, return, (lets say 5 hour journey) by train for less than 40 Euros with a weeks notice. A comparable flight cost would be 150-200 EUR. It's cheap, it's fast, it's convenient, and like the other poster stated door-to-door it's actually as good or better than flying.
By comparison, the US (And I see I was correct in my assumption you were from there - lol) has an absolutely atrocious train network and relies on planes for travelling similar distances. I wonder if you even remember that the original comment was simply a perfectly logical, correct guy just pointing out that lots of trains go over 200 MPH regularly. He didn't say it was the most efficient, he didn't say the promoters were angels who never lied, he didn't say it has a low carbon footprint, he didn't comment on which taxes paid for it, he didn't bring up standards of living. You're on a completely irrelevant rant, and what's worse is - all of your ranting is completely incorrect.
A useful comparison in terms of efficiency is Eurostar vs Flying (UK to Paris). The journey by train consumes 22 KG C02 per customer. The journey by plane consumes 244 KG C02 per customer. So you're ranting on about efficiency, carbon footprint, costs, taxes and standard of living yet your own system is more expensive, less efficient, larger carbon footprint, and your country has a lower Consumer price index than the majority of Europe. You need to get yourself educated before you continue spouting such uninformed nonsense.
