Futurology

Western democracy has revealed glaring problems with selecting governance, especially if the majority of the media is captured like in the US, and if elected officials have to beg special interest for money or be chosen / filtered through that process, or has to lie to the electorate. That China is doing relatively well despite being authoritarian, not having to be corrupted through that mechanism of election (an alternative might be sortition to prevent filtering for the worst vipers). But it's also lucky in that it's a "benign" authority still based on socialism and that it's not an enemy or plaything of the US. But even though it works for the people (for the people) it's not democratic (by the people)

Partially that is because China derives it's treasure from the people so education and productivity are important and with that some quality of life. There are plenty of pro forma socialist governments that only care to enrich themselves based on natural resources and can just brutalize and neglect it's population. So it's not just because of socialist ideology, it's where the money is for China. And afaik China still has it's corruption problems.
