This is the difference between Americans and many other cultures — there is a sense of self-reliance that often doesn’t exist in other places. Many people would prefer to let the government handle it as if the government was some omnipotent force with infinite resources that are positioned exactly in the right place: like battalions of Rangers sitting in a C130 at Hunter Army Airfield just waiting to drop into action. People underestimate the logistics of massive rescue operations.
Also, a practical question: how do you deploy 1000 boats instantly? Air drops? Does the government just have thousands of boats staged across the country with thousand of qualified operators ready to jump into action?
Americans as a culture are different — they don’t sit around waiting for “official” help — they jump into action. I’d personally rather count on some redneck with a boat than just hope government comes through. While bureaucrats are figuring out what to do, old Jimbo with his swamp boat is already in the water en route.
That’s America. You don’t have to agree with it, you don’t have to like it, but Harvey was a great example of the American spirit in action: neighbors helping neighbors — even local businesses, like Houston’s largest furniture store, opening their doors to help. In France, you would never see an IKEA or Auchan opening their doors to those in need during a disaster, you’d never see a virtual armada of volunteers ready to jump into action. During the great Europe flood of 2016, people died in their homes — wouldn't they have loved to have the Cajun Navy? In Triftern, Germany, 250 students were trapped in a school for 24 hours — I bet they would have liked to have some rednecks with swamp boats.
I am not arguing against government disaster response, I am arguing that in times of disaster, Americans, especially in the South, are proud to jump into action. Lives were saved because a whole bunch of people decided to act.
