The US government also actually tends to do a bad job* about things like this (i.e. evacuating citizen’s from foreign countries). So you have to pay the taxes but probably can’t count on the government to help. Now, I actually think all US citizens should pay their taxes, but it should be far more fair and reasonable than it currently is (we are basically just creating massive PITA for people while probably not catching offshore millionaires/billionaires.) The fact that you are forced to pay taxes but then will have to try to hitch a ride out of the country with Canada is unacceptable.
