I haven't been back to this thread for a while but saw a comment regarding how it's "easier" to get into US universities. Of course this is all relative and depends on your qualifications and which universities you are talking about. Once again, it is a distortion to compare a country like the UK that is about the equivalent of California in size, with the entire USA with its vast differences in geography, society, racial and ethnic makeup and history. For example the Southern states of Alabama and Mississippi will be annually at or near the bottom of educational results tables. However we clearly have to take into account the history of those states and the fact that economically they are some of the poorest in the nation. If you look at a state like Massachusetts 50.9% of the adult population has at least an undergraduate degree. When taken individually from the US and compared with other nations Massachusetts has one of the best educational systems in the world and a number of states can say the same.
Even Utah, a state with a very high Mormon population has a college educated population of 44.1% and is ranked overall in education in the top ten. Virginia, Iowa, New Jersey, Washington all these states are highly rated.
My own state has a college educated population of 45.6%. My eldest daughter just got into our flagship State University. It may appear to be "easy" to get into as the overall rate of acceptance is 45%. However students won't bother applying unless they have an overall grade of 3.85 (a 4 being perfect) which is in all their subjects in all 4 years of high school and equivalent to an A-/A. So my dd had to have straight As in math and German as well as all her arts and science subjects plus APs (college level courses). Some majors are extremely competitive and if you don't get accepted when you initially apply (straight to major) the university recommends you go elsewhere as it's extremely unlikely you can transfer into the major later. That includes: computer science, engineering and business (medicine is studied at grad level in the US and the uni has one of the best med schools in the country).
And how many students do they accept each year? 5,000. Yep 5k students in a state with a population less than London. Most come from within the state but about 30% are international students or out of state who pay 50k a year to attend. For in-state students it is 11.5k a year (currently about 9.4k sterling). The uni is ranked as one of the best in the world but probably most Brits have never heard of it.
I think Brits need to remember there are 50 states in the US. The US is still the biggest economy in the world. Also, if Brexit happens, with the fall in the pound I think you'll be seeing a lot more Americans in the UK as there is talk of Sterling reaching parity with the Dollar.
