How come paper cups can hold hot coffee for hours, but a paper straw turns to mush after 10 mins?

Just wondering about this as a I see a co-worker drinking multiple cups of coffee from same cup. And then whenever I get a drink while im out and then give me a paper straw, it becomes useless if I don’t finish the drink quickly.

Why do we not go back to the wax dipped cups we had in the 80’s? I mean I know this things failed after a few hours and I figure this is the real reason. Were they bad for us?
