Truckers as a group are not what most people would call privileged! Hard work, long hours away from their family, and not great pay. Most of them aren’t very educated and came from humble homes.
The protesters are, by and large, not truckers. There are some 300000 truckers (most of them vaccinated) in Canada. A few hundred of them are involved in the protests. It is not a truckers protest, it’s a people in pickups and passenger cars protest.
As for pay, I’m seeing wages of $85K + bennies advertised around here. That’s not a bad wage.
Comparing privileged truckers to Canadian indigenous people is chalk and cheese.
