Re: China and HS2
I can see the possible advantages.
I'm sure we are all aware of how our own construction companies, road repair organisations and the like tend to move at a snail's pace. I wouldn't like to say whether that is due to slow workers, a poor supply chain or inefficient bureaucracy, but the evidence of their lack of speed is everywhere to be seen, especially when there are miles of cones on our roads accompanied by no apparent workings or plant for months at a time.
I compare this to what I saw in Saudi Arabia. Gangs of Korean men could build a flyover in no time at all, certainly a lot quicker than ever happens in this country.
I don't know whether other workers and companies, Chinese or Korean, would charge more than our own. I suspect that, as well as completing work much more quickly, it would turn out to be cheaper as well.
Quite apart from all this HS2 nonsense which, of course, most people would never use, our money would be better spent upgrading and improving our existing lines, especially in the North which, needless to say, has suffered under-investment compared to Londonistan for many, many years.
