I fail to understand why you think China lifting people out of poverty and infrastructure work has anything to do with what Taiwan needs right now. But okay, I'll bite. REALITY CHECK TIME.

China lifter over 800 million people out of poverty.

Yet they are now facing a large wave of youth unemployment at 20.8% and is looking to get even worse. People are also not allowed to talk about poverty online, as a recent video on Chinese social media showing what 100RMB, the monthly pension and the only income one elderly has, could buy was taken down.

Majority of Chinese students who study abroad end up returning to China. Over 1,400 scientists have now moved from US to China.

Your linked article writes about privileged kids being able to study abroad but chose to go back to China due to cultural differences, work, family, or racism in America, has nothing to do with Chinese risking their lives to cross Mexico on foot to flee to America for a better life. In fact, the number of Chinese seeking asylum has shot up since Xi took power.
Also, this. The fact is the wealthy elites are also choosing to migrate to other countries despite opportunities at home. "反美是工作，赴美是生活", meaning "It's a job to oppose the US, but it's life to go to the US", is a criticism quote which is from a Chinese US-opposer who eventually also bought property in the US, that pretty much every Chinese and their dog jokes about now.

China also massively invests in infrastructure.

Sure. That's probably the thing that a communist dictatorship country can do best, I'll give them that. But again, what the fuck does that have anything to do with Taiwan and what it needs now? Last I heard, Taiwan is not a developing country, China is. Or at least that's what they demand they should be classified as while touting their record low of poverty rates.

What’s more is that 80% of these homes are owned outright.

HUGE ASTERISK HERE. In China, the land is owned by the government. Your home ownership is perpetual. However, the ownership of the land that your home sits on is leased by the government. Buildings for living purpose has a lease of 70 years, while factories and business purpose buildings have less. And those years include the time constructing the apartment, so the actual usable years are even less. Although their law stats that you could choose to continue the lease after 70 years, the government also has the right to take it back. Now, I haven't heard about any reports of related disputes just yet, but no one except the CCP knows what would happen 30 years from now.
