my salary hasn’t kept up with inflation

Yes, that certainly is a problem. Salary increases tend to lag inflation a bit, so you'd either need to switch jobs or wait to get caught up.

That said, wage growth has exceeded inflation for the last year and a half or so, so hopefully you'll get a yearly salary bump to help out. Our salary bump was higher than usual last year (about 5%), but still below inflation (8-9%), and I hope our salary bump this year will fix that (4% would be enough to catch back up).

But the fact that you've been able to stay financially stable despite high inflation means you're probably closer to "The Millionaire Next Door" than the average Joe drowning in credit card debt. If you can stay out of debt and put money away for retirement every month, you'll be doing fine in your 60s when you're looking at retirement.

you can budget yourself from the top of one financial class into the bottom of another one

Sure, if you follow the average advice (save 10%), then yeah, one bump-up is essentially expected. But if you're more aggressive, jumping up more than one level should be feasible.

This video talks about economic classes, and the portion I linked shows how you can go from $65k/year salary (middle middle class) to lower upper class by age 50 by just investing 10% of your income. So this is essentially middle middle-class to lower-upper class. If you do 40 years instead of stopping at 50, you'd have $3M by retirement age. If we account for 2% inflation, you'd have about $1.7M in today's dollars, which is almost to upper upper class. If you bump to 15% of your income, you end up with $2.6M after taking inflation into account, which is in that upper upper class range. So with just a median household salary, you can have an upper upper class retirement.
