This is why I still love Bill Nye. Eloquent, well thought out, to the point and has good reasoning along the way.
As far as welfare of any kind goes, mandatory drug testing would kick out A LOT of the people who are on it without good reason. To get most jobs, you have to submit drug testing, but to get FREE money (paid by those who've submitted to testing and work their asses off to see a lot of their paycheck go to taxes, some of it being for welfare) from the government, you only have to submit financial and/or medical records??
