Look at a quote just one group:

>"The largest group (9,143 businesses) is the professional, scientific, and technical services sector,"

If you add up all the categories mentioned you get 33,618 businesses above $1 Million

It's quite significant actually, if you visualize it correctly.

This article doesn't say there are 33,000 businesses making $1M a year (or you're right that's pretty small).

It says there are 33,000 businesses making a $1m a year that have only 1 full time employee. That's big.

Is it a commentary on the gig economy making 33,000 millionaires out of traditional business sectors? I'm not saying that's true, but something is shifting and it's big.
