What if, bear with me here, what if people just don't have as much disposable income after the dramatic transfer of wealth to the rich class we've been seeing?
The economy is collapsing and the lower classes are feeling it already. The rich investor class isn't seeing it because the tech industry has been propping up the market with their investments going all-in with unrealistic expectations for AI technology. We are currently experiencing a K-shaped recovery where the richest are on a spending spree while the poorest are cutting back their expenses. How much more obvious must it be that this is what's going on?
You want the general population to start wasting their money on useless crap again, you'll have to give them more money to work with.
