Phc7006: It is also clear that some countries aim at increasing VAT rate to compensate for the lack of growth .
Cavalary: That seems to always be a given, but I'm still wondering what are those finance people smoking to come up with the idea that higher taxes and therefore prices make people afford more and/or better things, to allow for the increase in product quantity and/or quality required for growth...
If you mean the staff of tax administrations, I don't think that they actually do have such ideas. Politicians are just pursuing short terms goals. If it yields them mandate, money and influence, they will be happy to pretend that we all live in a la-la-land where one can have a high level a state spending, low taxes and maximise purchasing power. But somewhere, some of them that we are all living and dancing on a volcano.
de_Monteynard: I agree that this may be a pain in the ass for many e-service providers, but the logic is sound. Since the financial crisis we have been fighting against banking oases that work on the same principle, ie. different taxation rates, allowing rich people to avoid paying their fair share of income back home.
The question of fairness notwithstanding, something similar can be seen in the digital market, with countries with low VAT collecting a disproportional part of all digital sales due to companies being established there. These new rules are meant to solve this issue and bring more equality to the functioning of the internal market. This was also noted by the article in the OP.
Any solution will remain an imperfect one unless VAT rates get harmonized ( except maybe for very specific locations, such as overseas territories )
As for the fairness of tax systems, when states pretend collecting 50-60% of the wealth creation through taxes and social charges, no system can be called fair. Such a taxation level is oppression , racket,...
