If the progs want rationing by all means they should go right ahead.
They can leave the normal American Citizens out of it OR, they can experience "rationing" at a whole new level.
.
What a fabulous experiment it would be if the elites ,defined as having an income of $150,000. Yearly and a post graduate degree, could illustrate by example rationing energy, gas, and meat.
They could practice this for 5 years. Everything they do would have to be documented, no cheating allowed. We would be able to see how well they did, at the end of the 5th year.
