Ironically green energy, EVs, etc is probably one of the best blue collar investments the country could make right now Industries in the US are at an inflection point, with govt / global market giving conflicting signals. For example car manufacturers need to decide whether to invest in EVs, which is a huge capital investment they won't see return on for maybe a decade. If they dont invest, they won't be relevant out…
People have been saying this for 20 years, and it seems plausible, but it hasn't really worked out (so far).
