Ironic then that most of the students throughout China who supported and even participated in the Tiananmen protests would later admit that Deng acted correctly in squashing it, and that China is better off today for that. This is a sentiment most Chinese living in China today share.

Could things eventually go south with the CCP in charge? Of course, and given long enough time, that's almost a certainty. But even when that day comes, it still does not directly imply a liberal democracy was the better governing system for the Chinese people, as your original comment strongly implied.

“ most of the students throughout China who supported and even participated in the Tiananmen protests would later admit that Deng acted correctly in squashing it”

That’s a very big claim to make without a reference.
