Losing retail jobs isn't really something a potus can stop.
Think about it. Now there's Internet, social media, etc. Amazon crushed all the other sellers last black friday. So this is infrastructure transitioning. Unfortunately for the people who are not adapting, human resources aren't needed in places where people aren't buying anymore.
I also don't think retailers are helping themselves much. I went to find a new computer the other day. I drove all around town because I wanted it that day.
I walked into Best Buy, Costco, Staples, and other stores. And do you know what the sales staff said? "What are you looking for?.. oh that's right here"... ok. That's it. No actual selling took place!! They just crossed their arms, at every single one of these stores, and did nothing else other than point to where the product was on the shelve.
Do you know what I did when I didn't see any great deals? I ordered on Amazon 2 day deliver.
Retail is on the way out.
