On the assumption he would follow through (apparently, previously promised money including DOGE cheques for those who effectively took voluntary redundancy haven't been paid - but I have not researched it so it could just be a rumour), and assume it would take around 3 months to permeate through the economy, it would represent a c. 3.7% of GDP stimulus to the economy, with a lot of people who will spend it. What happens when you add to the M3 money supply? Inflation. And putting that much more in - in a short period - would bring back visions of people in Germany in the 30s.. Well, maybe not as bad, but inflation will hit hard, interest rates will rise to try and stem it and that $5K is not quite worth what they think it is.
