That's completely counter to how capitalism actually works in practice. With every luxurious technology reserved for the wealthy there are always inevitably improvements in scale and delivery that make these luxuries accessible to the masses. Cell phones, cars, internet access, food delivery service, chauffeurs (in the form of Uber), airline travel, etc all used to be luxuries of the rich. In a short time, prices came down, and became accessible to most people.

Most of the wealthiest people in the world made their billions by selling something used my millions or hundreds of millions of people.
