1) Control over immigration
Majority immigration to the UK in the past years has been from outside the EU. We've always had control over that.
2) Our welfare system has been abused for years
Yes it has by people from the UK, but the cost compared to abuse of the Tax system is miniscule. Nothing to do with the EU, down to UK government.
3) Many markets has been flooded with cheap labour.
People have come here to do jobs UK population unwilling to do. Down to UK government.
4) The laws in this country will be made in this country again, we have thousands and thousands of laws that have been passed to us from the EU.
All of which we could have vetoed, unlike the WTO rules we will be forced to follow.
5) Now when someone commits a serious crime in our country they will be deported, currently they can just return.
Their return has always been under the control of the UK government.
6) I see the UK as a global country, with a rich history of relationships with the whole world.
You are right, it was that under the EU.
7) Politically we were always going to have to leave anyway.
Can you give me this weekends lottery numbers?
8) Many companies will thrive without the EU red tape strangling creativity.
See Q7. A few examples of creativity that have been strangled would be useful.
9) We can better allies in the longer term with countries in Europe not in the institution
Such as? Russia?
10) Your children and mine will inherit a country they can actually govern, rather than one that is cowering under the EU commission's rules
We can cower under US & Chinese rules.
11) The incredible amount of money we were paying in just to be part of the EU is eyewatering, and getting larger and larger.
We have wasted more money on Brexit than we ever spent on the EU
12) I do think we will prosper, and in the long term once we are over covid I see a greener, cleaner and more democratically accountable future ahead of us.
As we could in the EU, this is just opinion.
