This is a pretty negative post. We are at war now as we were one, two and three thousand years ago. Yes, it seems to be the way of the world but it's not as if nothing good has been going on for the last three thousand years!
More people live healthier, longer and better educated lives under better conditions than ever before. With the development of national wealth and technology, it's natural for manufacturing jobs to be replaced by service jobs. During my life, the USA has gone from a primarily manufacturing based economy to a primarily service industry driven economy. It's economic conditions that makes or takes jobs more than technology.
For these changes to be productive, adaptation is necessary. If you spent your whole life making buggy whips and cars come along and replace horse and buggies, you can cry about technology putting you out of work or get a job in a car factory. I'm not saying these changes are without pain, just that they are a part of life.
I think most people would approve of eliminating smoking in this country altogether. A nice idea but if that happens, we had better make room for a 100,000 jobs lost in the tobacco industry.
