Obviously the tax burden is a cost like any other cost a business faces. Higher costs make it harder to stay afloat. As a general principle, I think if you're going to raise taxes on the citizenry, you should have to face a vote in Parliament and face the music, so to speak. Otherwise, the public has very little recourse and very little defence against taxes that are raised automatically.
Yes, I absolutely agree that if taxes are going to go up, they should be voted on in Parliament so that they're on the record.
