They Lied, They Cheated, They Stole
They stole our future from US
For the same reason and under the dictate of efficiency things like, to pick a random example, the number of repair and maintenance facilities operated by the Deutsche Bahn and Berlin public transport both have been pared down to a minimum because having more of one kind for these manager types means redundancy that you can just throw out of the window. In this case it's the people who rely on public transport who have to pay the price (in terms of less reliable and BTW more expensive service) while said managerial class is enjoying the-sky-is-the-limit pay raises.
So I'm not a fan of the CCP and in particular not of their present leadership but it's not like the West hasn't be handing over their know-how and their means of production quite happily: for the managers it has so far nearly always meant better bottom lines and handsome bonuses. All the while everybody else has to believe that higher productivity will trickle down in terms of higher paychecks for everyone (which stopped to be true at some point in the past), and, as for China, the unfounded hope that somehow democracy will travel back to China in those half-empty cargo ships that are headed for Shanghai.
