If it is purely a question of paying the price, I can see nothing wrong with getting what you pay for.
If you choose to spend your own money on the things OP lists, that is your choice. I don’t see that as discrimination.
However, inequality lies in denying you a fair return for your labour, thereby ruling out huge swathes of society, it lies in discrimination which denies you access to even “joining the queue” let alone affording the price when you get to the head of it.
Communist countries in the past claimed to abolish privilege, to flatten out the inequalities of education, dress, housing, travel, title (everyone was “comrade”) medical care, employment - the lot of it.
Look at Russia and China today.
Equality?
To quote
“All are equal, but some are more equal than others”
Equality to me lies in establishing a level playing field where health, housing, education are accessible to all regardless of colour, creed , ethnic origin or finance.
