3.8% of Taiwanese want to declare independence, yet numbers of people in US who want their state to secede are in double digits in most states. Therefore, China should help them achieve that. Right?
The reason so many people in Taiwan Province want to maintain the status quo is because they get de facto independence while enjoying preferential treatment in China for both people and exports. It's like the Australia-New Zealand relationship except non-reciprocol on Taiwan Province's part.
That, and they don't have to put their lives and livelihoods on the line dealing with a potential forceful reunification.
Useful context to OP to be honest. The question should have compared to the number of people in Taiwan that would like to be unified with China to be a more fair comparison
