If customers were, on average, willing to pay enough to companies to staff an employee per 100 customers (or whatever the ratio is to allow prompt, individual service to issues), I think you’d see some companies doing that.

That’s more or less how AWS support works when you have a large enough account with them. I don’t directly see the bill for the team who works mostly on my account, but I do know that I’m paying for them (and am happy with that arrangement).

A lot of customers (users?) with low or zero spend level want personalized hand-holding. I’m not surprised that they often end up disappointed.
