Maybe things like health care, crop subsidies, mortgage interest deductions, and no-doc loans are similar. Can Congress read? Is there a study that determines exactly how big a committee has to be to strip itself of all intelligence? I admit, I’m a small government libertarian and a fan of tax simplification. I think we’ve skipped the Occam’s Razor phase of legislative drafting, sometime about 200 years ago, and gone straight to the “we’re geniuses and can finely orchestrate systems we don’t even understand.”
The economy and human behavior are not to Congress as a poem is to Humpty Dumpty:

My health care prescription, assuming you want to expand the availability of health care in the US? Just change the maximum income qualification level for Medicaid. One number.

Why bother?
