Yes, crisis management jobs are going to become increasingly plentiful over the next decade. The reason being, given the state of the world, is that there are likely going to be increasingly plentiful crises that need to be managed. Between weather and natural disasters, wars and military occupation, terrorism and who knows what else, crisis management jobs are going to be critically important over the next decade and beyond.
I do think this is a field and position that's going to really open up over the next 10 years. With how hectic every day life is becoming, it's going to be a growing concern and necessity to hire people who can manage crises. Expect to see this position grow exponentially.
I don't think there will be an increase in crisis management jobs. Now we can manage crises better then we do now but I don't think the solution to that problem is to hire more people. We just need to do a better job with the people we already have.
No, crisis management jobs are not going to become increasingly plentiful over the next decade, because that is something that is usually handled by the government. There are only so many crisis that are going to happen in the world at one time. There are technologies that help us handle it more efficiently.
