No, he is not really and we will see.
As I said before, its just because we human beings are usually scared of change, so we often need some time to adapt.
For example before we joined the E.U in the 70s many people were saying the same thing about how our economy is going to collapse and decline into oblivion if we joined the E.U, how we are going to lose all our sovereignty/laws etc, some even said if we don't adopt the Euros we will be doomed. Yet none of that happened, our economy grew, our currency is the worlds 3rd largest reserve currency and among the top 3 most iinfluential/used around the world. Etc
So all these fear mongering is just fear mongering. lol. We will carry on moving forward even if we are not in the E.U. In fact, it may do some good, hopefully this will make those unelected arrogant E.U Commissioners to take other E.U member countries complaints about reforms more seriously next time. Lol
DO note thar if we were never part of E.U then people wouldnt be saying all these doomsday scenario like what they are saying today. Lol Since they will all have been used to it. Lol Anyway they will still get use to it, and 5-10years from now everyone will even forget they ever predicted a doomsday scenario. Lol
Moreover, the real reason most brits voted out was because of immigration (70%) and sovereignty(20%) to be honest. It was a mistake to admit other eastern European countries in so early, since the difference in standard of living is quite wide. If E.U had first restricted itself to western europe while advancing towards the East on a case by case basis with time as gtheir living standards improvise, then we would all have been far better off, and no brit(mostly the common man) will be complaining so much about so many immigrants taking their jobs and lowering their wages. This is what tipped the balance as well.
At the end if the day we need to seriously review oyr immigration policy and follow Australian or even Canadian model of high skilled immigration depending on skills, experience and what value they and bring to our country or through a case by case basis.
This also applies for migrants from non E.U countries coming here
The world is a very big place.
Too bad the U.S is not in our commonwealth.
lol
