Ooh, an economy alarmist bullshitter.
Before the Civil War they said freeing the slaves would ruin the economy. The US had to free them because it was a moral imperative. The war cost us 5% of the US population in casualties. The sum total of the monetary value of all slaves at the start of the civil war was roughly one trillion dollars in today's dollars. The slaves were freed and the US became the world's greatest economic power as a result.
Fast forward to today. The oligarchic elites (the Koch brothers and other greedy billionaires) control roughly fourteen trillion dollars in fossil fuels. In order to monetize their investment they need to suck it out of the earth and burn it. The resulting pollution would kill at least millions, if not render the entire planet uninhabitable. There is a moral imperative to not do that.
If one trillion dollars was sufficient to justify killing or wounding 5% of all Americans, I shudder to think how many people the Koch brothers and their friends are willing to kill or wound for fourteen trillion dollars.
Our economy was based on slave labor. We emancipated the slaves, and surprise! We prospered anyway. Now our economy is based on generating poison gas from fossil fuels. When we stop burning fossil fuels, I predict we'll prosper anyway. Maybe not the Koch brothers. Oh boo-hoo.
