And it is by and large their own fault. Not Obama's or Clinton's or nobody else's. Their own. It could be different.

If Real America doesn't wish to subsidize my decadent coastal elite lifestyle that's fine, but I shouldn't have to subsidize obesity either it raises my health insurance costs. The Northeast has some of the lowest obesity rates in the country so fair's fair.

sounds like a rather facile notion of how economies work. "Capitalism" (in quotes) in the US is heavily top-down already, to the point the interests of industry vs. government are often indistinguishable. See also: crony capitalism.

It's also hard to get good data points on how well-managed socialist economies work in third-world countries; in the 20th century at least the US shows up and bumps off the leadership and sets up puppet dictatorships before anyone who seems like they might be good at the job gets much of a chance.

Saudi Arabia is a de-facto socialist state just about everyone who lives there is on the government's payroll in some form or another don't hear too much complaint about them, they're one of our best friends apparently.

Sure, I consider food to be a quasi-engineering kind of discipline, there's at least as much science to it as there is art

"Cooking for Geeks: Real Science, Great Hacks, and Good Food Paperback" by Jeff Potter https://www.amazon.co.uk/Cooking-Geeks-Science-Great-Hacks/dp/0596805888 Some of that is relatively hardcore, e.g. which proteins bugs survive which temperatures.

Nonsense, Gaddafi was in the middle of a revolution BEFORE a score of countries (at French insistance) did a relatively mild intervention. A US secretary of state at the time, Hilary wasn't there when Gaddafi died. As for laughing, that's just free speech - recall, Gaddafi DID confess to the Lockerbie bombing, which is a NATO offense we oughtn't forget.
