Mark your calendars. The rich will truly "have it all" just 33 years from now.

Yup, that's when the top 10% of all households could have 100% of all the net worth in America.

I learned that when I projected the rate of gain over the most recently reported three-year period from the Federal Reserve Survey of Consumer Finances. The last survey was completed in 2016, and it measured the change in shares of net worth from 2013 to 2016. It also showed the changes in every three-year period since 1989.

However you slice it, the rich have been getting richer. Lots richer.

Here are the basics. From 2013 to 2016, the top 10 percent of households increased their share of total wealth from an amazing 75.3% to a stunning 77.2%. That's a share gain of 1.87% in just three years.

If they continue to gain share at that rate, they'll have the remaining 22.8% of net worth held by the other 90% in just 12 more surveys, give or take an upheaval or two.

But don't be depressed. Look on the positive side. When that moment comes, most people won't be concerned with mortgages or car payments. College for kids? Fuhgeddaboudit. Retirement savings? What's that?

Nope, 90% of Americans simply won't have to worry about junk like that anymore. Talk about easy living!

But don't get overconfident. As a newspaper reader, a person known to actually read, you may not qualify to be in that bottom 90%.

Where you stand

Fortunately, it's easy enough to find out. Just go to one of my favorite number-freak websites, dqydj.com, and use its online calculator to see where you stand on the net-worth pyramid. (Dqydj, by the way, stands for "don't quit your day job.")

The broad figure for being in the top 10% is $1,182,390.36. You can also get an age-appropriate figure by using another version that calculates net worth by age. You'll be in that worry-ridden top 10% zone, for instance, if you are 35 to 39 and have a net worth in excess of $368,093.19.

Some readers will think these figures are pretty low. There are ZIP codes in this country where that much is parked in the driveway. But in real America, the net worth air gets thin really fast. If you have a net worth of $97,225.55, you're ready to join the top 50%.

What about the next 9?

A still closer look at the share of net worth figures reveals another problem. The table I've shared here shows the changes in net worth shares from 1989 to 2016. While the share of the top 10% has grown consistently over the period, the share held by the next 9% — the folks who don't quite make it into the top 1% with $10,374,030 — peaked in 2013 and declined slightly in the last reporting period.

What does that mean for the next 9%?

Maybe nothing.

But here's my guess.

If your quest is infinite, unlimited wealth — a quest that seems to define the central life goal for many members of the top 1% — then you have to be thinking about the source of your future wealth gains. With the bottom 90% now holding only 22.8% of all wealth, the pickings are pretty slim.

The next 9%, however, look like low-hanging fruit. After all, it's a small group — only one-tenth the size of the 90% — and its members hold 38.53% of the wealth.

So if you're in the next 9%, gird yourself. The squeeze is on, and you're next.

It will stay that way until we no longer worship wealth.
