So the whole less taxes less corruption thing isn't my argument, but I think they meant less taxes as in the number of different taxes you can give breaks from, not the total percentage burden.
The potential for tax breaks ultimately depends on the total amount you’d potentially pay. (Edit: even this isn’t the limit. Nothing says you can’t give companies more than they pay.) How it’s divided up doesn’t really matter.
But those who advocate for more taxation, how do you stop this kind of corruption?
