You might be able to argue that higher taxes encourage tax evasion.
Of course it is a factor.
A person looks for work, they consider what they're going to end up with in their hand after taking into account how many hours are going to be occupied doing that work, how much it cost to get to work (in time and money) then they decide whether or not it's worth their effort.
They draw a line in the sand, on one side they say "Yes I will be better off doing this job, I will take it." on the other side of the line they say "No, not enough in it for me."
Along comes the state bureaurat twiddling the tax dial, an artificial cost, for every 1% they add to the tax the line moves and a bunch more people decide the job is not worth their effort, reduce the tax and a few more people decide yes it is worth their effort.
Hiking the tax for people doing good things is no different from hiking the tax for people for doing bad things. It's a disincentive. You're one of those people with their hands held up to each side of their face refusing to look at the damage being done by taxing good things.
