No, the US didn't have the manpower for manual review. Further complicated by our federal system, with most social programs run at the state level. Even more complicated by a decades long effort by conservatives to make state/local programs difficult to use because everybody should just pull themselves up by their bootstraps. The closest we could come was the stimulus checks that went to anybody with a prior-year's income below a certain threshold (IRS has that info).
