I've personally worked in a University Department that was tasked with marketing to international students and can say that this is entirely true. To the point that the school reserved a certain number of spots exclusively for out of state/international under the guise of diversity. In most schools it's not even where you think it is, recruitment and admissions had little to no control over us. We had a direct line to the top and were actually the ESL program, we gave students who graduated (the ESL program) a guaranteed spot in whichever college they wanted within our university, and we would take basically anyone who paid.
So if you wanted to short circuit the regular admissions process and are willing to pay you'd apply to our ESL program >> spend 4-6 months there >> pass through because $$$ >> enter your bachelor program of choice at a fairly high state school.
UK and European 3-year Bachelors are merely a means to an end, i.e. a 5-year university education that is comparable to doing a 4+1 year BS+MS, which is an option offered by many American universities. Very few European students apply straight to a Masters program in the US after completing their 3-year BS.
You can blame second zone universities that have become a visa mill for students ready to pay an expensive ticket to the US job market. And there are definitely issues with underprepared international students, especially regarding languages skills and the very different expectations compared to their home country. But there's no need to be demeaning.
