Imagine all the people who lost their jobs when farm mechanisation happened or people who lost their jobs shovelling horse manure of the pavement when the advent of cars. Change happens. There are gainers and losers when any change happens. Some retailers will adapt to sell products we value or in a way we value and some will not.
A bigger problem is the percentage of the profit from on-line sales that will to be going off-shore. But then EU has its investor community to blame. Investors here tend to see 'tech' as too risky so do not support start-ups and as a result we have no home-grown on-line retailers so choice but to use those from overseas. Yes, of course, some bricks and mortar outfits have grudgingly and slowly moved on-line. But not in any way that one could call innovative.
