I'm sure Tavares would be a lot happier to contribute his tax dollars if they enriched his life, or if he actually had confidence that his tax dollars were helping the Canadian state function. An ArriveCan scandal isn't really a big deal, just a drop in the bucket really and governments are run by fallible humans, it's that we're taxing ourselves into the ground and yet have failing healthcare systems, a military in absolute shambles, rising crime and falling public trust, and as a nation we spend hundreds of millions of dollars on evangelizing feminism in the Middle East. Or pouring tens of billions annually into Indigenous projects that somehow accomplish very little to improve the lives of our Indigenous people.
Taxes are essential for the functioning of a state. We need roads, public education, Canadians are (or were) proud of public health care, and societal safety nets. A military to protect our domestic sovereignty and to project power abroad (soft power needs to be backed up by hard power). Plus some more to handle the various bureaucracies that help a nation of tens of millions function with a semblance of smoothness. All that costs money and people need to pony up, which the rich overwhelmingly do, but people also deserve to get good results from their taxes.
The rhetoric about "the rich need to pay their share" is deeply, deeply toxic, because the simple fact is that they contribute massively, and that their dollars do actually entitle them to some expectations that their money is being spent properly. Canada has been drunk on tax and spend for years and years now, and what are we actually getting for it?
Squeezing millionaires and billionaires for more money would be virtuous if the nation was starving, or the nation faced an existential threat of an enemy. But we don't have that, we just have a lot of people with their hands out. Canada must have the courage to ask itself what value it is providing to its citizens for their money, and remember that the rich are entitled to a fair social contract like the rest of us.
