Yeah I mean the key phrase is “as much.” 
If let’s say being “rich” is having $2mm in assets, and your parents have $4 and other people who own cape houses have $3, well you’re all rich, even if they’re less rich. 

If you’re saying many objectively middle class people (on a classification we all agree on) then I’d see your point. At the same time think of it this way, both rich and poor people live in say NYC, a super expensive city. But some life in tiny cramped shoeboxes and some live in very nice apartments.
