> Instead, what I think has drastically changed over the past 40 years or so is the ability of a solopreneur to make real money.

Hard disagree.

As the article notes, I think if you concentrate on a real business, not a scam-y 'get rich quick scheme' business then, especially with the internet, its never been easier to run a solo business at scale.

For myself, I wrote an app as a side hobby, which then took off, so I started working on it part-time, then moved to full-time when the revenue justified.

It's now growing to where it exceeds what I would have made working for someone else.

Note this took 7+ years of constant work, improvements and care.

It's the type of dedication that makes you competitive with even larger organisations.

And the time required to be a 'success' ensures that you won't have any competitors who just want to make a quick buck or get to "passive income" within a year or two.
