Keep in mind the fraud is in the hundreds of millions and the size of the program is in the hundreds of billions ($260B from the CARES act alone: https://www.nelp.org/publication/unemployment-insurance-prov...)
If it's 200M of fraud that's less than a percent. I don't think you can safely say less than 1% of Americans have had their identities stolen so they've done a hell of a job if you ask me.
