I love Steve Benen. Read this, then hop over to his site, read the rest, and you'll see why:
If we cut spending on volcano monitoring and tsunami warnings, we save a little money on maintenance, but pay a lot of money on damage repairs after disaster strikes. If we cut spending on food safety, we save a little money on inspection, but pay a lot of money on health care costs when consumers get sick. If we cut spending for the Securities and Exchange Commission, we save a little money on enforcement, but pay a lot of money to clean up financial catastrophes.
He's clear as a bell, logical, and gives great blog.
