If you're in the top 1-2% of income earners you feel things differently, this is understood.
So while your math is good, it's not meaningful. I find it very weird the lengths people will go to in trying to make one-off metrics reflect a different reality than what is very clear from people's experiences.
But job switchers (rightly) give themselves the credit for their salary boost. OTOH the government gets the blame for inflation and job loss. It's a crap job, you get blamed for the bad stuff, but don't get credit for the good stuff.
Suggesting that people job-hop is insane. Most workers cannot do this for a multitude of reasons, and most jobs are fungible. It's a very keyboard-warrior way to look at the economy, which is like getting advice on which car to buy from hedge fund managers.
Have you talked to low-wage workers? They switch jobs a lot. Long-term job stability is actually more of a corporate white-collar phenomenon.
In any event, others disagree with your chart: https://www.pewresearch.org/short-reads/2018/08/07/for-most-...
That's literally the point of adjusting for inflation. You can of course pick the fastest growing components of the CPI (housing is already a huge component) and complain that we're not outpacing the fastest growing component, but that's arbitrary.

That chart looks at wages rather than income, e.g. excluding healthcare contributions. You can argue that we shouldn't count healthcare because it's gotten way more expensive for no real increase in quality (which is true!). But healthcare is a huge and rapidly growing component of CPI which we are using to deflate wages -- you can't have your cake and eat it too by excluding healthcare payments from compensation but including it in your deflator.
Also that chart just seems to be wrong (they don't actually show the source or data). You can do the comparison yourself easily enough -- take the average hourly wages (https://fred.stlouisfed.org/series/CES0500000003) and use FRED's graph editor to compare to a deflator (e.g. CPI -- https://fred.stlouisfed.org/series/CPIAUCSL). This is up ~10% since 2008. It's not massive but it's not nothing -- and remember the caveat above that this is an underestimate.
And re: switching jobs for low-wage workers -- either they are getting big raises or getting big pay increases from switching jobs, or the BLS is massively wrong. Which is it?
The numbers are meaningless, even if they are accurate, which I sincerely doubt. GDP is up 5%? My salary hasn't gone up 5%, but my grocery bill has gone up way more than 5%. Health insurance costs went up more than 5%. Maybe all those increases in prices are boosting GDP, but wages aren't keeping up. Maybe the numbers are hand-waving nonsense.
People know whether they are doing okay or not. GDP is a blunt instrument metric of little value except as a broad comparison. But noting that it "happens during a Democrat presidency" is quite telling.
