Seems a bit harsh. There are any number of reasons for which people choose to see providers:
1. Want to fuck the hell out of a girl - Fine, English not too relevant.
2. Want side benefits - Fine, doesn't take that much English to say (1) Do you want a greencard? (2) Here's a Chanel bag and a stipend or (3) I'll write you good reviews with my 10 TER accounts.
3. Want a simulation of an emotional connection together with the sex, without the complications of doing it for real - I think there's actually a lot of mongers who see providers for this, especially at the $400 range for what is supposed to be GFE, not PSE. It's a lot harder to do this when her vocabulary is limited to "You too big for me" "I"m dizzy, you knock me out" "You nice guy, I wish you could stay longer" and "This is the first time I do this kind of job, back home I'm normal girl".
