Why do people think new phones are expensive?

I was tired of my iPhone 8 Plus so I just bought an iPhone XS, not the max version because I thought it was too big. But anyway, my bill is $28 a month and I put $200 down for the phone. Someone commented why would I buy an expensive phone. But I can pay $30 a month, it's not that much.
