Retail replaced by online shopping. For big ticket items, yes, it will take a huge chunk out of the retail market, but the need for physical shopping will still be there. Ever buy clothes or shoes online? Unless you know how to sew, you may need to find a seamstress or tailor to adjust those clothes. Sometimes, you can't wait for the package to be shipped. Retail stores have a need to fill, the immediacy of the buyer, so will combine brick and mortar like Walmart, or revert to mom and pop shops. Retail will adapt. But for those warehouse locations, expect those workers to make demands on higher wages instead of earning minimum wage.
Next time you go into a restaurant, see how many high school kids you see working. At one time, they employed mom's trying to add to the family income or high school dropouts. Around here, they're now hiring using the warm body method. They were looking for college grads 8 years ago. Had a real long talk with the marketing manager of Burger King a few years back. Not much different from this conversation. I've noticed a big difference in the local stores since then. Unless they're a target to be Romneyed (Ponderosa Steakhouses, 1986) restaurants, including chains and franchises, are in business toake money, and that requires customers. I rarely eat out as I spent enough time in food service to be a damn good cook. That's coming around. Right now, only one person in a restaurant needs a food handlers license, but that can change at any time. (Locally. Laws my vary from state to state, and e en witbin the state)
Manufacturing? First, forget about the hnions. They have no clout anymore in the manufacturing businesses. Oh, sure, Ford and GM, but look at the drop in membership from 1970 to today. No, they didn't ship everything overseas. Union busting. Or move to another state. No, unions are just a boogie man that industrialists tell their children about to scare them. Non-issue these days. If they were powerful, Hillary would be the president elect. As is, I'd wager that more than half of all Union workers, past and present, voted for Trump because of the way the Democratic Party has treated them the last 40 years. So, where are the manufacturing jobs? Look in the non Right To Work States. Sure, you've got some in RTW States, but nothing like the non RTW ones. Factories around here are clamoring for help, and most are staying here because the workers are higher skilled than, say, Kentucky or Kansas. (Cont)
