I stopped at a Wal-Mart (WMT) the other day on my way to Napa Valley.

I am not normally a customer of this establishment. But I was on my way to a meeting where a dozen red long stem roses would prove useful. I happened to know you could get these for $10 at Wal-Mart.

After I found my flowers, I browsed around the store to see what else they had for sale. The first thing I noticed was that half the employees were missing their front teeth.

The clothing offered was out of style and made of cheap material. It might as well have been the Chinese embassy. Most concerning, there was almost no one there.

So I was not surprised when the company announced that it was closing 267 stores worldwide. The closures amount to only 1% of Wal-Mart’s total floor space. Some 10,000 American jobs will be lost.

The Wal-Mart downsizing is only the latest evidence of a major change in the global economy that has been evolving over the last two decades.

However, it now appears we have reached a tipping point, and a point of no return. The future is happening faster than anyone thought possible. Call it the Death of Retail.

I remember the first purchases I made at Amazon 20 years ago. The idea was so dubious that I made my initial purchases with a credit card with a low $1,000 limit. That way, if the wheels fell off, my losses would be limited.

This is despite the fact that I knew Jeff Bezos personally as a former Morgan Stanley colleague. And how stupid was that name, Amazon? At least he didn’t call it “Yahoo”.

Today, I do almost all of my shopping at Amazon (AMZN). It saves me immense amounts of time while expanding my choices exponentially. And I don’t have to fight traffic, engage in the parking space wars, or wait in line to pay.

It can accommodate all of my requests, no matter how bizarre or esoteric. A WWII reproduction Army Air Corps canvas flight jacket in size XXL? No problem!

A used 42-inch Sub Zero refrigerator with a front door icemaker and water dispenser? Have it there in two days, with free shipping.
