It can be especially difficult for businesses and the people they want to employ when there are strict limits on the number of visas for each profession. You might have a great person who desperately wants the job but after several months of bureaucracy you find out this year's allocation of N visas has already been allocated and you are N+1.
The way Indian service companies get around the immigration visa rules is by sending people over on "temporary assignments" under the Intra-company transfer (ICT) rules which are subject to the work permit cap. Once we "take back control" that could easily happen with European companies where people are hired by a German subsidiary then "loaned" to the UK office for a few months. This really isn't good for business continuity as you get a constantly changing staff working on a project.

Yes, the USA is a desired destination for many young scientists from Europe as that's where many companies have their main research sites. However, it is very tough to get a visa (and may get tougher still under Trumpism) which makes the UK as an attractive alternative.
