Are you suggesting that's a problem that needs to be avoided, or just pointing out the unfortunate downside? To me this is a lot like jobs that are becoming obsolete and/or phasing into alternative solutions, such as coal mining. I think it's unfortunate if people and/or towns are losing their livelihood or their income and careers are dissolving, but I don't think it wise to try to prop it up and support something that isn't working or isn't sustainable just for the sake of propping it up, or just because there are negative consequences. Now, if the reason those things are dying out is partly political, then certainly minimizing the political impact of that is appropriate, but landscapes change for a multitude of reasons. If urban areas struggle economically as the dynamics of employment change, what to do, beside finding different ways for those urban areas to be fertile soil economic growth?Yep, which will lead to another round of urban flight similar to what occurred in the 1960's.
I can tell you that ****ed up NYC for about 25 years
