Amazon e-commerce market share 2016: 38%, 2018: 49%

What's the US market share of the largest offline retailer?

Also, consider this chart: https://www.thebalancesmb.com/worlds-largest-us-retail-chain...

Walmart, Costco, and Kroger are bigger than Amazon in terms of revenue. (Kroger only just.)

> But if Amazon.com exists and is generally useful, why would people go to another site?

Why wouldn't they? What's stopping them?

I agree we may need to reconsider some of our laws to better take into account online behaviour. But Amazon should not be penalised for mere success. They ought to be penalised for abusing market dominance if that is indeed what they are doing. No abuse, no penalty. Questions about tax payments on the other hand… Amazon have nowhere near the quasi-monopoly in their sphere that Microsoft has in desktop operating systems, Google has in web search, and Facebook has in social media.
