Yes, I get that but, ultimately it's going to take too long to get to the point where it benefits the people that need it the most or, A lot of the extra money generated will stay in the companies and people will see very little or no benefit from it.
'VAT free shopping for overseas visitors' is about benefiting foreigners - it's chucking them a sweetener to get them to spend their money here.
I just think that our own should have the same or better terms than we're giving to foreigners.
