But I do not believe everyone will quickly find an even better job when a factory closes because 1) popular perception aside, that is not what happened in the industrial revolution and 2) it is not what happened with globalization 3) it is suspiciously pleasant and easy belief for those who are least likely to be hurt. It's also a bit magical thinking.
And if wage depression from globalization has caused damaging ethnic and nationalist backlashes, it's not hard to imagine the multiplying effect that will come with reckless displacement due to automation.
Because people who have a continuing or sudden drop in quality of life due to events beyond their control are not going to blame themselves forever and are not going to be convinced by a rising GDP graph that leaves them further behind.
Great would be a society that everyone feels vested in and an economy that everyone can participate in. But it's hard to imagine any such plan being invented let alone honestly implemented in the foreseeable future. Are thousands of 50 year old factory workers going to get hired as a web designers? Are they going to work as Walmart greeters thinking "sure I lost my house but national wealth is up so I don't mind". So at the very least there needs to be more adequate social safety nets.
