Whereas with taxes, if you don't like them, you can elect a different politician. Look at the Americans, they do it all the time, their tax rates go all over the place.
I want roads, libraries, firetrucks, and for my poop to vanish into oblivion when I pull the toilet handle. I don't really want my money to buy my boss a new car.
Not necessarily as easily as you can vote for a different politician, especially since you're restricted by your ability to change locations (family, property, heritage ties), or industries. And in this day and age changing employer very well may not at all mean you're changing who's extracting your value or how much.
Government meanwhile, at least in a liberal democracy, is fundamentally designed to be petionable and changeable. Thus "we the people." Of course I would agree that this system has been utterly corrupted by neoliberalism and corruption ("lobbying"), but I'm talking at a theoretical level here.
Voting is easy. Of course that doesn't actually do anything, you're entirely held hostage by the 51%. Unlike switching jobs, which is entirely consensual and determined by you. If you dislike the arrangement you made with your boss you are more than welcome to leave at any moment.
If I dislike the arrangement made by 51% of people my only option is to leave - an option that I have to pay exit taxes in order to exercise.
