What would happen if we all put on yellow vests and protested in the streets?
Governments would panic and hand out printed money since that’s their only option for providing more stuff in the short-term. As a consequence, the riots would stop, CO2 emissions would immediately increase, and a few months later currency destroying inflation would begin, which would increase social unrest and enable a despot to take over (a la Weimar), who would attempt to increase prosperity with war, except this time war will not help because we’ve already burned all the good booty, and we would enter a scarcity death spiral since war will deplete faster the resources we are fighting over, and finally a few decades later, runaway climate change would take out whatever is left of civilization.
What if governments responded by taxing the rich and redistributing wealth to the poor?
Most of the wealth of the rich is locked up in assets that do not circulate within the economy. If these assets were liquidated and redistributed the poor would immediately spend their new wealth which would dramatically increase inflation because there is far more paper wealth than real wealth in our economy. As inflation destroyed the currency, social unrest would increase leading to the same death spiral described above.
