Like different theories, supply-side economics isn’t flawless and does have some holes. Listed here are 5 key the explanation why the speculation has been disproven.

Tax Cuts Don’t Create Extra Jobs

If corporations are taxed much less, they’ll use their extra financial savings to make use of extra workers, argue supply-siders. The issue is there isn’t loads of proof to again that up.
