The FAA gathers taxes per person, not per plane. So a commercial flight has every single passenger paying, while a private jet only pays for a few people. That’s a difference of about $2300 for a commercial flight, vs about $60 for a private jet. Private flights make up about 7% of air travel, but contribute less than a tenth of a percent in taxes. But the air traffic controllers aren’t handling individual people; They’re handling planes. So private jets fund the ATC a lot less than commercial flights, even though they have just as much need.

This video says Canada taxes planes based on weight rating and distance traveled. So larger planes that can carry heavier loads (more people) get taxed more, while smaller planes (private jets) get taxed less. But they’re proportionally paying the same in taxes, instead of the rich people paying less.

Just don’t use accounts the school knows about…how hard is that? Don’t use the shitty equipment they give you because it’s loaded with spyware, haw hard is that.

From the article (emphasis mine):

The research team identified 14 companies actively marketing online surveillance services frequently beyond school-issued devices and outside of school premises, raising concerns about privacy, equity and oversight

Sounds like they’re using heavier tracking than simple device tracking. Probably lots of fingerprinting, which can be extremely hard to avoid; If any of your accounts even touch the same network as the school device, they likely track it.
