Fair enough, but mid sized cities have jobs for plumbers, electricians, government employees, secretaries, marketing people, accountants, college professors, construction, biologists, vetrenarians, etc.
The title, "The Middle Class Can't Afford to Live in Cities Anymore" is absurd.
Thus they either have to deal with periodic un- or under-employment, or manage the risk by building a cash cushion, either of which means a less affluent lifestyle.
There are plenty of suburbs within a 10-20 minute driving distance from the city. Also, businesses operate in those surrounding suburbs.
I like mid sized cities. Not too large, not too small, but just right.
I pay around $1600 monthly for a $227,000 house in Austin, so the housing cost would be $19,200 / $41,000 or _46%_ which is absolutely not 'affordable.'
If someone making the median income in a city can afford a median house with 21% of their gross income, yes, I deem that "affordable."
To go back to my example, the family making $41k net annually is paying $10,800 (ish) annually in mortgage costs. They pay an additional $4,781 in property tax annually. That leaves $25,419 annually or $2,100 monthly for other costs and savings.
My example makes plenty of assumptions that won't necessarily hold (after all, I'm assuming averages here). Notably, I'm assuming a 20% down payment and excellent credit. And no, that's not a lavish lifestyle. But it's well within the realm of "affordable" for an average person.
I'll also note that $228,000 is the median price, but a search on Zillow shows >1500 listings for less than $150,000. I saw one listing for 3bd/2ba at $135k within the loop. near decent schools and within 20 minutes driving distance of downtown, the USAA and Valero corporate campuses and the UTHSCA medical center, all major employers.
I don't really see what your example has to do with my point. Yes, Austin is more expensive than SATX. Yes, someone making $51k should not pay $1600 a month in housing cost. But you're making my point for me—housing costs in medium-large cities are not necessarily out of whack average incomes in all such cities, just some markets (like Austin).

I was using it as a starting point.
That said, other industries are geographically concentrated as well. If you have your heart set on working in the oil business, you probably shouldn't set your sights on living in Boston.
It's not just that different industries have their hubs - media, design, finance in NYC, entertainment in LA, tech in SF. A whole ecosystem of supporting firms grows around these companies. So the most influential and prestigious law, accounting, and consulting firms tend to cluster in these cities too.
There also are a lot of people who don't necessarily want to spend their entire lives in, say, NYC but think it will be a good career move to get a prestigious name on their resume before going somewhere else.
At this point I think there's kind of a chicken and egg situation where a lot of ambitious, talented people flock to major cities because firms are there, and firms stay planted in these cities because so many talented, ambitious people are flocking there.
