A lot was written about the stimulus checks but they were so small to not matter. A $1200 check isn't going to suddenly lift a lot of people out of poverty and keep them there, even though it could be make-or-break for a few selected cases.

Remember "The Great Resignation" when everyone was changing jobs because all the companies were hiring as fast as they could? It was an ideal time to move your way into a better position in the job market.
