I think this is all tied together with the thread on ChatGPT.
These leaders all know that 20 years from now almost all jobs will be done by robots, drones and computers and AI. Therefore they don't need any more children. Hence the vaccine.
They know that the best way for them to balance their books and eliminate debt is to get rid of the elderly. Hence the pandemic and vaccine.
They also know that people are not going to agree and will protest. Hence the vaccine contributing to them being able to track every person and surveil them.
What is the pay off to these leaders to be so draconian? The tests for Covid were actually genetic tests making a file of every persons genome and so they will easily be able to find a match for an organ for these elderly leaders. This is what the Chinese already do. They don't waste time looking for volunteers who are a match, they already know who is a match and they just go get that organ when needed. You thought when they said "you won't own anything" that this didn't include your own organs? Why would you make that assumption?
