Walmart is the largest private employer in the world. A sudden collapse would probably be at LEAST as disruptive as a sudden collapse of GM or GE. But I think we're at an impasse here because of some subjective evaluation of the goods or services that a particular company provides, which actually is not as relevant as its being made out to be when talking about the economic impact. I personally don't think that much of what tech does is a systemic risk anymore than brick and mortar retailers, but the size of a tech company could be relevant to systemic risk.
If Google were to have a sudden failure tomorrow, it
could be a systemic risk because of the
uncertainty that it would present to all of the people and companies who depend specifically on Google for their livelihood. Google's intellectual property would still exist, and it would be quickly snapped up, at a discount, by other companies. So there's not really any risk that we won't have a search engine if Google disappeared. Market cap is just what the stock market thinks something is worth, and many humongous companies don't even have market cap because they are privately held. But effect on the real economy is revenue.
The exact same thing is true of Walmart, whose most valuable asset is probably its name. If Walmart were to suddenly collapse then all of the employees, goods manufacturers, etc., that depend on Walmart to pay them and/or distribute their products are at an extreme risk of collapsing due to the uncertainty that would exist if Walmart suddenly disappeared. Walmart is a special case because of its size, but the same is true of any other company with far reaching
human impact. Although not perfect, revenue is a better measure of the
human impact than market capitalization.
