Thanks for this. I do hope policy makers understand that differentiated 
pricing is fundamental to markets and allows businesses to recover their 
investments. This is found almost everywhere, from Saturday night stays 
with airplane flights to mountain bikes (where the Specialized Epic 
Cross Country has price points from $6,000 to $11,00 for basically the 
same bike. https://www.specialized.com/us/en/c/epic?productfamily=Epic)

I think a major difference today, at least in developed countries, is 
that wealthier people aren't motivated by fear but more by status. So we 
don't need to put poor people in a stowage class anymore to get to 
differentiate pricing. Wealthier people (and some members of SCOTUS) 
desire a "higher class" status and will pay for that status (or have 
their benefactors pay for it.) The wealthier typically have to go early 
and pay more. True for the Model T, computers, etc. Those higher prices 
help pay off the investment. No early adopters then no early majority 
and no late majority.

Regulators serve the majority by assisting with differentiated pricing 
which seems counterintuitive to many (which I think was your point.)
