My talking points are mostly from subject matter experts with good track record. Yours is generic youtube wisdom from ADVChina and laoway86.
> makes no sense.
Tell that to various international global rankings in innovation / research indexes that controls for quality and impact factors. China starting to lead in many strategic high tech fields. High impact research doesn't seem to have a problem citing Chinese papers. Espionage built the base and fills in gaps. Combine with domestic research = rapidly propelling Chinese RD competitiveness. Whine all you like, strategy is working and reflected in reality. Not to mention industrial policy is modelled after west, China likes to copy what works after all, it just learned to play the same game well.
> China's growth was helped mainly
Yet it grew to 2nd largest economy, 1st by PPP measures. Model worked in China but not India who had better starting conditions. China had exceptionally onerous WTO accession protocols, sanctions and other geopolitical hindrances. Ultimately it's about playing cards that are dealt, which were much less charitable than your fantasies. CCP just managed cards competently and continues to, seeing how FDI is up, minimum amount of foreign companies are moving out despite cold war, Chinese companies expanding abroad, trade deals being signed, further entangling more economies to Chinese supply chains. Demographic crisis overblown, China's a medium income country with plenty of room to grow, enough cheap surplus labour to maintain infrastructure and negotiate demographic transition. Meanwhile western infrastructure actually rotting, living standards are declining. See which countries are actually losing shit over economic anxiety, fracturing over immigration to maintain unsustainable safety nets and coping with rants like yours. China isn't a developed country, it's not going to deal with developing country problems based on poor projection. Poor Chinese are going to die poor, but still richer than they were. That's an arguable easy crisis to deal with than pervasive decline in QOL in west.
> outsourced that with industrial espionage
Again refer to steady upward trend of Chinese academic institutions. China only middle-income country to break top rank. Mid-ranking universities have converged and started to outperform mid-ranking western institutions. It's just getting started.
> what's the fucking benefit
Just 40x increase in economy since 90s and massive aggregate QoL improvements I guess. Maybe also triggering folks like you. Hundred millions = urbanization rate from 60% -> 70% by 2025... then onto 80%. That's 300M people... Remind me how much surplus units there are? Obviously some waste, but broadly oversupply was planned as part of general urbanization strategy trying to get rid of subsistent farmers kept around for stability maintenance.
> always end up costing more
Said every China collapse proponents every year for the past 30 years, yet somehow China is now a viable strategic competitor to US.
> Chabuduo constructions are crumbling
Actually worked in construction field in China / West. Residential developments in North America failing as much as ones I've worked on in China. Except China builds it cheaper and faster. BTW most of South Korea has shitty construction quality due to rapid development. It's been decades, unsurprisingly not actually an existential problem. Not to mention the amount of seemingly unworkable starchitect designs in tier1/2 cities that are doing fine. Hint: construction isn't rocket science. Some accidents as result of building more than the world combined or US in last 100 years is negligible. I'll take that over NIMBYism stagnant infrastructure/development any day.
