I took the phrase “small business” to mean places with an actual storefront (restaurants, small shops, studios, and so on) who use FB or IG in lieu of having their own site. For those places it makes particularly little sense because social media isn’t most people’s first port of call when they’re looking for somewhere to eat dinner or go thrifting.
If you switch that last Fed graph to show the percentage of total wealth instead (which accounts for inflation), the under 40 category is actually at it’s highest level since 2013. It looks like it hit all-time low around 2010 at 4.8% and has steadily increased since, at the expense of the 40-54 demo.
