A high altitude nuclear detonation can wipe out all electronics within a fairly large area.

That is somewhat of a myth. An EMP can damage electronics attached to antennas or long power lines that can act as antennas. But an EMP will do little or no damage to isolated electronics, or to electronic devices that include countermeasures, such as shielding and isolation circuits.

Everything I was taught about Christopher Columbus was wrong! Damn public school education!!

I attended public school, and remember learning in 5th grade that Eratosthenes of Alexandria accurately calculated the radius of the earth around 200 BC. In addition to changing shadow heights as you move from south to north, the curve of the earth is visible against the moon during a lunar eclipse. Both the Ancient Greeks and the Romans were well aware that the earth was a spheroid, and knew the approximate radius.

Either the school you attended was exceptionally bad, or you spent a lot of time not paying attention.

Would it help, just a little, to have rain catching devices hooked up to houses to provide water for toilets?

No, not near enough to justify the cost. Most residential water use is lawn irrigation. People should get rid of their grass lawns, and use xeriscapic plants. My yard is mostly rocks and cacti. The only irrigation is for my vegetable garden and fruit trees, and those are all drip irrigation, so they likely use less water than if the same fruit and vegetables were grown commercially.

So the difference between being Rich and being middle class would solely come down to the house.

Warren Buffet still lives in the same modest suburban house that he bought in 1958. So I guess that makes him just a regular middle class guy.

My grandmother had a better heuristic: Paper towels. According to her, when you can afford to buy paper towels, you are no longer poor.

Is that a lot? I mean compared to rainfall over that area.

It is about 10cm or 4 inches spread over the entire state.

There are 264 gallons per cubic meter. So 11 trillion gallons is 4.16e10 m^3. California has an area of 424,000 km^2, or 4.24e11 m^2. So divide the volume by the area, and you get the depth = 4.16e10/4.24e11 = 0.098 m or 9.8 cm or about 4 inches.

I live in San Jose, and we have gotten more than 4 inches of rain in the last week, and it is still raining. There are areas of California (the Mojave Desert) that get a lot less, but also areas (the North Coast) that get a lot more.

Mexicans come here to bring a piece of Mexico with them, wanting bilingual schools and lots of other accommodations

This is complete nonsense. Bilingual education is deeply unpopular among Latinos, who overwhelmingly prefer English immersion for their kids. Latinos are transitioning to English just as quickly as other waves of immigrants in the past, such as Italians, Germans, etc. You should read some history books on the Italian speaking tenements in Brooklyn a century ago. People then were spouting the same xenophobic nonsense that you are today.

Do you let random people walk into your home any time of the day or night without knowing who they are?

If not, why should the United States?

That is a ridiculous analogy. You could use the same argument to say that every state, city, and neighborhood should build a wall to control who comes and goes. And "knowing who they are" is not the same as tearing apart families that have been here for a decade or more, working hard, and being (otherwise) law abiding.

And since you asked, yes, I do let "random" people stay in my house. I have sponsored two Naxi girls that came to America as students, and are now permanent residents. I will be sponsoring another immigrant next year.

At what point do we have the right as a sovereign to say 'no more, we are full?

We are no where close to "full". Most immigrants settle in cities, and the population of most cities has actually fallen in recent decades. Detroit has lost 60% of its population since 1950. A half million hard working Mexicans would be a huge boost to that city.

When is the cut off to you?

A long, long way from where we are now.
