Sooty, that is an insulting comment. The regime I would like to see, as you put it, is one that has the common sense to realise that a country of banking centres, call centres, museums and shops alongside high tech innovation and manufacturing centres owned by foreign companies is not, long term, a recipe for national success.
We live in a global economy and companies will always make decisions on where they operate and what they do. Joint ventures are obviously the way forward when looking at the costs of new projects in any major engineering area or in infrastructure. The problem for the UK is that whilst it is a centre of excellence in so many fields, ownership of most major economically and strategically important industries is in the hands of foreign concerns either totally or to a major degree.
How many aircraft, road vehicles, trams, trains, power companies, telecomms operators, food providers and many more essential products/services are either wholly or mostly British owned? Frighteningly few. What is lacking is a balance.
Back to BAe, its reason for scrapping the RJX was spurious in the extreme. That apart, the country has lost a strategically important industry and the expertise that goes with it, not just for now but for the future.
