That's not an accident. In the last 1-2 decades, the largest generation in American history started retiring en masse. They didn't have enough children to replace them, because the birth rate peaked in 1965. This generation is now drawing off of retirement savings, the vast majority of which is backed by ownership in equities and bonds in publicly-traded companies.
When you don't have more people to provide value that includes a sale, like you say, and still have to increase value of equities and bonds every 90 days, you have to more intensely monetize each customer.
It's only going to get worse unless you bring a lot of people into the market as new potential customers, but you can only do so much of that without causing social disharmony.
