Follow up thought, Kevin:
Church indulgences had their roots in cheerful giving. Lots of cheerful "carbon giving" going on right now too; in fact, I’d call it downright prideful (which is why giving to God always had this condition on it).
That cheerful giving morphed into a guilt-giving, and was ultimately mangled by the Guardians of Truth intoਊ grotesque, compulsory tax on the faithful.
Will we see a similar pattern emerge here? Would not be surprised. Nor would I expect such a tax to be limited by national boundaries.
