You ask what ‘federal and state programs’ I would be proposing to end. Perhaps you live in the USA. I, however, do not. And my article is not country specific. I have a good idea what I think should be done in the UK, but I am certainly not an expert in the schemes you have over there in the US.
Have a good one! :)
