World leaders are largely not serious people OR malicious.
Instead of asking why their societies are having less children below the replacement rate (fiat fiscal & monetary oppression), which threatens the fiat ponzi of neo feudalism. They decide to import people that as a result of fiat colonialism imposed on their own countries are willing to accept an even lower standard of living as an upgrade. Which is a double whammy to existing citizens.
Instead of asking why the majority of citizens are unhealthy (corrupt gaslighting in support of fiat food & disingenuous "body positivity"). They call for subsidizing lifetime GLP-1 persecutions with questionable & largely unknown side effects for people as young as 5.
And when all else fails they instigate WW3 and attack our rights.
