we exported $37.1B worth of vacuum tubes last year. I could be wrong but that amount seems wildly implausible. Could the category actually be "Vacuum tubes, etc." where "etc" is semiconductors?

The Chicago fois gras ban ended in 2008.
Not just possible, it's actually quite common, and has been for awhile. For example, see this article from 2004:
Yes there is. If this plan goes through, S&P will downgrade Greece's credit rating from CCC to SD ("selective default").
The poverty line sets a minimum level of consumption. These people are consuming above that threshold, so i don't think the government counts them as poor.
> If it weren't, consumption would be equal to income + change in net worth.
You're forgetting change in asset prices. If i own a house, and consume all my income, my net worth can still change if the price of the house changes.
This cohort doesn't appear to be very poor at all, in fact -- they report negative self-employment income. I wonder if you've confused low income with poverty. Or perhaps i'm confused, and haven't grasped your argument.
[0] I'm taking welfare to be the sum of "Unemployment and workers' compensation, veterans' benefits" and "Public assistance, supplemental security income, food stamps".
Hmm, i wouldn't call it totally arbitrary. UTC = TAI + LS, such that |UTC - UT1| < 1 second, where:
* LS are leap seconds,
* TAI is "physicist" time, based on the ticking of atomic clocks at mean sea level. The length of a second is constant.
* UT1 is "astronomer" time, the rotation angle of the Earth with respect to the quasar reference frame. The length of a second is not constant.
The Earth's rotation is slowing down, so UT1 is gradually drifting away from TAI. UTC is a pretty natural scheme to reconcile these two systems.
