> I think one of the problems facing specifically Walmart is that their multi-decade long negative sentiment at the corporate and personal lives of the executives among social progressives that are strong among the "millennial" demographic in the US undermines a lot of the innovation that the company does.

Nah, that's limited to upper middle class millennial who can afford to "buy local" and buy fair-trade coffee. If you walk into any Walmart in the country you'll see a lot of millennials shopping there because it's cheaper (and in a lot of places its essentially the only store in town).
