Amazon can't count employee taxes
How many fewer employees of brick and mortar retailers are there in the UK thanks to Amazon? Those need to be subtracted out for a fair accounting.
Same thing with small businesses. If I opened up a restaurant in a tiny little town that had one restaurant, and drove it out of business with superior food & service, I can't say "look at all the jobs I created". I also destroyed jobs in the old restaurant, and on balance it might be a wash.
