That's a long term issue that shows it's effects in terms of years (job migration), not a short term issue such as week long (and longer) power outages. Why the people in the Sudan and countries in that area don't leave is simple, there is nowhere for them to go (migrate). Similarly, many folks in NJ, NY and CT have nowhere to go or the means to get there, so they wait for the power to come back on. Meanwhile, more gas stations have come online and the lines are short to nonexistent. There are others that are still trapped as I write this in neighborhoods blocked by downed trees tangled with downed wires that are humping everything they need in on foot. Still not enough power crews to go around. Everyone's situation is different, there are no simple solutions or "one size fits all" approaches.
This is becoming circular, adieu!
