What is the motivation behind the cheating and plagiarism? This would seem to imply that students do not care about learning the underlying skill. Why would a country encourage this?
Indeed, the notion that you would go to university to "learn", or god forbid, continue learning irrespective of employment and wage opportunities, or pay money for learning that didn't have an employment or wage outcome, would be seen as some kind of mixture of stupid/bad decision/literally non sensical.
University, and academic publications and structure, makes a lot more sense once you accept almost no one there is interested in knowledge.
That's why the USA and UK should oppose efforts to allow students to stay in the country after they graduate. International student graduates should have to go through the same migration process as anyone else.
Additionally, Governments should place a cap on the number of student visas they issue each year, require universities charge a minimum amount, and require the full three years be paid upfront. Universities will be more willing to fail poor students under these conditions; it will also prevent/reverse a race to the bottom.
