The upper class in Denmark are just as big piss babies about paying their taxes as they are anywhere else. Ordinary Danes might like to say they’re happy to pay taxes but in reality few of them would pass the opportunity to have their car fixed off the books or to buy beer in Germany to avoid the Danish alcohol tax.
This has been tried many times and history shows that it’s a really effective way of getting yourself couped and get a brutal reactionary regime put in your place. The bourgeoisie is not burdened by any high-minded liberal ideals when it comes to preserving their wealth and power, they are going to do whatever it takes.
