No kidding. Airlines added hundreds of thousands of jobs in the '80s and '90s as air travel became affordable for everyone with a job, instead of being an expensive luxury. It's been great for consumers and bad for the employees of the airlines that haven't been winners over the past 10 years. It's also been great for all the people hired by WN, B6, FL and all the other growing LCCs.
Wagon wheel and buggy manufacturers hated the auto revolution, but those car companies ultimately hired millions of people. Sadly, their fortunes have also waned over the past 30+ years as Americans fell in love with cars made all over the world instead of just those built in Detroit. Change bites for those married to the past. Change is wonderful for those who anticipate it and profit from it.
