From the beginning of civilization all the way up to the end of medieval times, leaders understood the importance of jubilees: Every generation or so the concentration of wealth under a hierarchy gets so bad, so unbearable, that debt must be relieved across society by decree to prevent open revolt.
Nation states were the end of all that. The merchants (Today we call them capitalists) are not the figureheads of society the same way that kings were, they don't fear for their lives when they order politicians to double down on debt, issue new currency endlessly if they must, force through any economic hardships in order to prevent the relief of worsening inequality, to prevent the endless accrual of their wealth and lifestyles.
Instead of relief every 50-odd years, we've been hurting more and more for the past several hundred because nation states provide a faceless, unassailable aegis for the top heirarchs that never existed for them before in history.
Yeah, it's already deployed on slrpnk.net. I see it momentarily every time I load the site.
