My current read of the situation is similar. If you go to other countries, there are slews of small shops, even in run down areas. On top of that, in places within Asia, the malls are also open and full of regional chains. It also feels like there's such a wider variety of certain goods available, because the little bakeries are doing their own thing, while in the U.S. seemingly everybody is eating Costco danishes.
"Passive income brain" people are not the only one's trying to "build revenue engines," that same sort of talk exists in corporate America. There are already people that that own companies which are there "to generate passive income for me," right now--there's a whole class of millionaires and billionaires that don't have to work. Passive income people didn't ruin the "content quality of the entire internet" and are far from the only ones doing so. Many of these folks are likely the ones that would have owned a hardware store if America didn't ignore it's regulatory duties while preaching about how "important" small business is.
In the U.S. situation really seems to have fossilized into a few big players/platforms, and they continue to freeze up through the process of things like private equity roll-ups. There's a thread on the front page right now about Amazon's alleged price-fixing tactics, which hurt customers and small businesses. Further: Real-estate is an investment, so for most being able to pay commercial rents is a pipe dream. Healthcare is tied to employment, so people are less free to try and start something other than "on the side."
American's choose "convenience" when shopping and to put people in power that serve these large companies or their owners, not small businesses or communities. Dropshipping, creating a "sweaty startup," etc... it's all just people trying to make do within the system they're trapped in.
