That's been, pretty much, what I've been telling everyone since the crisis started. Actually, it's even more a no-brainer than you suggest, because at the beginning of the crisis, it would have been particularly helpful to the very people who were hit particularly hard by the crisis, ie people from the building sector.

Their skills would have been immediately useful in making existing buildings far more efficient. At essentially zero cost. We have wasted 7 years and counting at a time when every passing month is a stab to both our present and future.

Earth provides enough to satisfy every man's need, but not every man's greed. Gandhi
