It seems to me that some companies could turn a very nice profit from an evacuation plan.
Let's say, for example, you needed to evacuate a million people from Houston to higher ground, say an hour away from the city. This could be done with one or two days notice by about 2,000 buses. These could be existing school buses and other buses used for public transportation. Private automobiles would be banned from the evacuation routes while the buses were being used for evacuation. And if there aren't enough existing buses, more could be built (at a nice profit) for standby emergency use.
Then there would have to be enough storm-proof and flood-proof buildings erected to temporarily house the million people. Here's where the real money would come in, and of course, since public money would be used, the cost overruns would be enormous and would yield correspondingly enormous profits.
If we had single-payer, I imagine it would be rather like Medicare or Medicaid for everyone.
Mediocre, and soon to go bankrupt.
And of course, the rich Nomenklatura in Canada can always go south to the US for critical medical procedures.
