Except for things that we have to import, e.g. food,
I’m far from Jamba, but if we weren’t in the EU food prices would be through the floor due to oversupply (and a lot of farms would be out of business). I’m not a fan of the CAP, i think it would be better implemented along the lines of the small brewery relief scheme, whereby small farms would be offered subsidies to make them competitive against agribusinesses, and agribusiness would be left to fend for itself. The net effect would hopefully be lower efficiency/productivity (which keeps people employed), and smaller, more diverse farms which are better for the environment.
The price of Spanish tomatoes may go up, but the price of home grown produce may fluctuate either way.
And hey, you can grow tomatoes on Teesside (it’s actually quite clever, one farmer even manages it as a byproduct of electricity generation, but that’s a long story!)
and things that are traded in other currencies, e.g. oil,
Yes, but we produce (some of) our oil, which is going to make the north sea slightly more competitive, and make our oil and gas industry competitive (as an industry we export a lot of expertise as well as just the black stuff).
I always find it telling that people who play up the positives of a lower exchange rate (and yes I know that there are some) are pretty slow to point out the negatives. I wonder why that could possibly be!
There’s a lot of crap going on, but the pound falling like a stone I think will be a blessing in disguise.
