Indeed, Hooray! (I'm glad you get it - so few kneejerk anti-American morons do.) The US is at its best when it is saving innocent people, like Libyans and Yhazdis, from genocide. It returns us to what is best about this country.
Yes indeed! Your quote IS bullshit! I'm glad you noticed! You can't claim a policy failed by arbitrarily changing the yardstick. We've never measured by U6. No time to start now.
Hooray though, we added 300,000 jobs in the last quarter. The economy did that in most years of the 1960s, when the population of the United States was significantly less than today. Success!
Yet again, you are completely correct! This is an amazing Success! The economy in the 1960s was aided by the fact that most of the rest of the world was still recovering from WW2, and half of it was under the ideological sway of Communist regimes fundamentally opposed to economic reality. Further, the U.S. had many more controls in place in those days to reduce economic inequality, since people still had a long memory of what Republicans did to cause the Great Depression. Tax rates on corporations in the 1960s reached as high as 90%, with fewer loopholes. This allowed many states to give a free college education to anyone who had the grades to get accepted, no matter what their economic background. All which provided massive demand for U.S. employment.
Alas, we ended all that. Self-defeating "trickle-down" is now more or less a religion (except Jesus and his miracles can't be actually disproven, like all these bullshit Republican economic theories have), so now we're stuck with people voting in Republicans on grandiose promises that this-time-it'll-work-for-sure, the inevitable economic crash, Democrats voted in to fix it, and then Republicans again to punish the Democrats for fixing the Republican mess, because this-time-it'll-work-for-sure.
