The trouble here is that context is
expensive. You have to not only look at what the rule purports to do but also what it actually does in practice, including the second and third order effects.
But the people who have time for that are the incumbents, so you end up with rules that on their face are supposed to help the little guy and in actual fact do quite the opposite.
Here's an example. It's a common trope that consumption taxes hurt the poor because they spend a higher proportion of their income so we need to use income tax. But if you look at the numbers, the upper middle class spends the large majority of their income too. You don't get to people who only spend a small fraction of their income until you're into the investment class -- and those people don't pay income tax either. Partially because of transfer pricing and things like that, but at root because they reinvest whatever they don't spend and business expenses are tax deductible. So the claim is BS.
Meanwhile the huge advantage of a consumption tax is that it's hard to avoid. What rich people actually do when there is an income tax is minimize their "income" and buy on credit, which in many cases lowers their taxable income even more if the interest is tax deductible. Whereas with a consumption tax, if you want that yacht you're paying the tax whether you took out a loan for it or not.
So the powerful put out this propaganda that the tax they would actually have to pay is the one that hurts the poor and the one they have many ways to avoid is the one we need to use. But ordinary people aren't all that familiar with how rich people accounting works, so they buy that theory and fight against a change that could shift more of the tax burden from the middle class to the rich. There are also a bunch of things about how the income tax on capital gains benefits not only rich investors but huge conglomerates, on and on.
So unless you have some way to counter this information asymmetry -- and as yet this appears to be an unsolved problem -- the default presumption has to be that a given regulation is inefficient or corrupt. Because most of them are.
