I grew up there, and I was there last weekend for my Dad's memorial service.... I hadnt been back to Tahoe City for some time - and man, its freaking depressingly bad.
The "mall" -- the Boat Works, has basically 4 shops any longer, the retail spaces near Tahoe City Golf is boarded up and has weeds - many retail spaces are empty, the freaking BANK had to close, restaurants arent doing well according to several people I know who have worked in them for ~35 years (at SunnySide, for example)....
and all my Dad's freinds/contemporaries blame SV Money + AirBnB -- in that there are no places for anyone to live. Houses arent being rented to people who would want to live there - both seasonally or long-term.
All the cheaper houses were bought up over the last decades and rebuilt with $1MM++ homes in their place (This happened to one area which was the "ghetto" in the 80s when I was a kid - where all the houses were replaced with >$1MM homes and became one of the most expensive zipcodes in the country - whereas it was where all the "poor" kids lived in the 80s)
