The land cost alone for hs2 runs into the billions, it’s just very expensive to do.
Do you believe the land costs in France, Spain, Germany, China and Japan weren’t expensive?
China is not. The CCP can just seize the land and force you to accept a pittance in compensation.
I genuinely can’t continue this conversation in good conscience given the fact that I don’t have sources. I can only go off of some YouTube documentaries I watched once upon a time where the government made a valuation on some land, sent in some archeologists and rehoused residents taking them rural living conditions with an outhouse to newer houses with toilets. In each case I saw the government deemed the projects more valuable than the people’s land/houses and time has proven them right as they have high speed rail and economic growth in all areas the rail network extends to and beyond.
You only mentioned china, where they don’t report on land costs because all land is state owned but yes I do believe land compensation is much less in china, not least because HS2 land compensation is significantly above market rate. Also; an authoritarian regime with only superficial regard for the health and well-being of their workers, that are paid almost nothing is certain to be cheaper. Suggesting otherwise is banal.
