There is absolutely nothing stopping the USA getting off its fat ass and competing all those fields,
Apart from the inherent laziness corruption and inefficiency of a country infected with an over powerful financial sector.
Stop looking at China and bleating about how somehow it isn't fair, step up and compete.
The USA has squandered its lead in almost every field apart from hubris, thrown away the advantage of reserve currency and geopolitical security and finds itself in a spiral of decline. You cannot stay rich, dumb getting weaker indefinitely, someone wll come and eat your lunch. So it goes. Smart money is hedging accordingly.
HK is being used as a stick to beat China by the Anglos, it is an open secret that most of the protests are funded and backed by those same wonderful arms length organizations and NGOs that caused shit in Ukraine, in Venezuela and elsewhere.
A bit of history, for over quarter of a century Legco in HK has not put in place a security policy which allowed the autonomous region under one nation 2 systems to work. This is something Legco were obliged to do and agreed to do but in order to appease HK independence blowhards Legco didn't do it. There is not significant support for independence for HK, and even if there was it would only be the Island not the New territories that were just leased from China anyway. without the new territories HK island cannot function.
For a long time China turned a blind eye, but more recently the Chinese government has lost some of its tolerance. Nobody seems very clear what the 'democracy protesters' want, just like the Maidan protesters in Kiev...China is not going to allow Anglo agitators to pull the same stunt in HK.
To be clear HK Island was stolen from the Chinese by the British as a consequence of the Opium wars, HK is part of China and this is a Chinese internal matter to be sorted out between HK and Beijing, the UK and US would be well advised to sort out their own broken countries before getting involved in sorting out some other countries problems.
Tibet is not in the news, but on Tibet China most certainly no legitimate claim but Tibet is never going to be independent again. It was dubious deals with the British and external agitation that ultimately lead to China properly annexing Tibet, in 1959. So history doesn't bode well for interfering with HK.
It is foolish to try and create a new cold war, and a new divided world between Orwells' Oceania, East Asia and Eurasia, East Asia will ally with Eurasia or Eurasia will stay non aligned, either way Oceania loses what little it still has.
The Chinese didn't take US blue colllar workers' jobs, financially connected insider elites took US blue collar workers jobs and gave them to China so they, the financial elites, could profit. Until people recognise where the problem actually lies they cannot fix it.
