Selective numbers again. You just can't help yourself, unless of course you just don't understand numbers of course.
Taking out inflation, one pound in 1970 is worth 16.60 in 2020.
UK GDP in US$ (inflation adjusted) was about $1bn, pre-covid crash it was about $3 bn.
The contribution per capita has increased only a faction of what you are trying suggest from the bare figures. Of course the EU is also a much changed entity from 1973 too, and the benefit the UK economy received has increased enormously in that time esp..sectors like financial services (which thanks to Brexit is in the process of being dismantled). Well done you.
