Ethical issues of putting people out of a job? Please. This mindset has to be called out because it directly causes suffering via creating a societal permission structure for politicians to protect interest groups with protectionist trade policy and internal pork barreling policy. Economic productivity putting people out of jobs is both good and necessary and it is unethical to work against it.
My favorite example of complaints about "putting people out of jobs" is that's an argument against self-serve gas in New Jersey (and recently Oregon).
There should be social safety nets to ease people's transition. Not protectionism of unproductive jobs.
