If you are outside of the EU, my understanding is that it is harder now than it was say a year or two ago, as we have now adopted a points system.
I think that the poster's enquiry is less about how easy or otherwise it might be to immigrate into Britain and more about how easy or otherwise it might be for an immigrant to get work in that country (although the suggestion was also made that the intent was to come to Britain to study).
Under our previous government, everyone was let in
That's not true. There have always been rejections of aspiring immigrants to Britain, although I accept that more may be turned away nowadays than during the life of the previous British government; there are, of course, still illegal immigrants and no government can prevent that or has prevented it.
as we needed workers to do jobs that some lard arse Brits did not want to do
And we don't any longer?...
Anywhere near London is incredibly expensive to live in
Indeed it is, although my curiosity as to the enquirer's present location is fired by the suggestion that "everything is cheaper" in Britain and I can only conclude that this present location might be Denmark.
and if you are looking to improve your English, you would struggle to find a native speaker in some areas
Nonsense! In any case, there are plenty of places offering lessons in Englsh to foreign students.
Unless you are Scottish or Welsh, study fees have risen considerably
This is indeed true - quite absurdly so in certain places, in fact - although something tells me that the enquirer is neither Scottish nor Welsh...
Your best bet would be to invent some story along the lines of that you were tortured in your Country and your grandparents were eaten by government forces
Once again, you seem to be getting the wrong end of the stick (or maybe even the wrong stick); no possibility that the actual act of immigration might pose problems has yet been mentioned, so why assume that there would be such problems?
Under the European Wrongs Act, we would be unable to deport you
The Act comcerned is the Human Rights Act but nothing therein prevents justifiable deportation; if an immigrant has broken certain British and/or EU laws while in Britain, he/she might risk deportation.
you could live a life of luxury on benefits
No one lives such a life on state benefits alone in Britain.
Another good idea would be to buy a cat when you get into the Country, so you could claim your right to a family life would be infringed if you were deported.
That's about the most absurd reason for feline acquisition that i've ever read.
Saying this, unless you are living in Libya, I would stay where you are.
Only Libya? What about Syria? Sudan? Nigeria? Iraq? Afghanistan? Iran? North Korea? Rural China? Any number of other countries you could mention? In any case, the poster was not counselling your opinion (or indeed anyone else's) as to whether or not to immigrate into Britain but asking about work possibilities there and mentioning comparative costs of living and incomes.
Best,
