I guess to be fair, there are some local places around me that make sodas, which probably are reasonable ethical businesses. Depending on how many bourbon colas you’re drinking, it might be worth paying extra for an locally made soda if possible. If you don’t have someone that makes soda locally (which is probably likely), maybe consider buying from “gourmet soda” brands like Hank’s.
I wonder if even some red states would stop paying as a result. I can’t imagine Ohio and Pennsylvania being ecstatic about propping up the Mississipi, Alabama, etc. after California, Illinois, etc. stop footing the bill.
