> if there's a revenue threshold bake it into the law
There's no real winning there either. If you bake the threshold into the law, some companies may game the system such that, if the cost of total compliance is x, and we're revenue range of x, give or take, to just take a little less money to stay under the threshold.
Not that I'm suggesting that is something that we should care about, or even consider a majority worry, but hard and fast cliffs lead to gamesmanship, or worse, misaligned incentives (such that it's non-beneficial for those on welfare to work if it puts them over a given benefits threshold.)
On the whole, I agree that selective enforcement is bad, if not wholly terrible, but its absence isn't a panacea either.
