The truth is that most reformers prefer fairly simple rules. In the tax world, they’d prefer to simply tax all income. In the environmental world, they’d prefer to set firm limits for pollutants. In the financial world, they’d prefer blunt rules that cut off risky activity at its knees. But businesses don’t like simple rules, because simple rules are hard to evade. So they lobby endlessly for exemptions both big and small. This is why we end up with tax subsidies for bow-and-arrow makers. It’s why we end up with environmental rules that treat a hundred different industries a hundred different ways. It’s why financial regulators don’t enact simple leverage rules or place firm asset caps on firm size. Those would be hard to get around and might genuinely eat into bank profits. Complex rules, conversely, are the meat and drink of $500-per-hour lawyers and whiz kid engineers. If the rules are complicated enough, smart lawyers can always find ways around them. And American corporations employ lots of smart lawyers.
