This sounds like half word salad and half martyr/hero complex something or other to me. Why don't people just spit out what they've found or think they've found from the get go and have it over with? The drama is pretty useless.
I don't recall the liters for gas, but I remember the rationing and the Time magazine cover warning about the coming ice age. '77 or '78 I think, and when gas doubled and shot up to 68 cents a gallon I thought my hot rodding days were over. Somehow we survived without AOC or Greta. Maybe we were just tougher then, kek.
I'm old enough to remember when President Jimmy Carter, while sitting in the White House and wearing a sweater, told us to lower the thermostat in the winter because we were going to run out of oil in a few years. Climate change then meant the Earth was getting colder.
They mention that communication was so slow it took until June for the people in Galveston to hear that slavery was over (simplified take, but still). They never mention that the Republican party was the one that made it happen, along with untold multiple thousands of dead white men in a Civil War. Or that the first slaveholder was a black man named Anthony Johnson (they'll argue technicalities), or that the first 23 black Congressmen were all Republicans, or that the KKK is the creation of the Democrats.
Also not mentioned is that a "Juneteenth" couldn't happen again today because the White Devil has made communication nearly instantaneous.
Anyway, the answer is pandering. That's why it's now a national holiday. Pandering.
"OK listen. Part of the plan, you see, is to secretly arrest and try certain individuals in secret tribunals. If they are found guilty we secretly execute them for their crimes, but then we replace them with doubles that go out and commit the exact same crimes as the originals did. And it's OK because the crooks are dead and it's now the good guys committing the crimes!"
