I think you've hit the nail on the head here and with another point in a previous post. It's not the wages that are the issue with the fruit and veg picking, it's just the sheer physical nature of the work involved. The average brit is not fit enough to do it. Most that need the employment choose not to do it, even if they were offered more money, they'd rather get slightly less money to sit at home on benefits. Such is the mess of a system here.
Just compare the physical shape and size of the average hardworking immigrant to the average obese British Benefit Bum. Unsurprisingly, I've heard a few times now that employers would much rather use foreign labour because of their output and work ethic.
A personal account from this weekend that illustrates the above. So we went for a walk up a well known large Shropshire hill yesterday, as it was a lovely warm day. There were hundreds of people at the top but we were the only ones using our own two feet to get there, apart from one cyclist and one crazy fell runner. The rest were a load of blobs in cars, almost nose-to-tail driving up to the top and back down again. Pausing only long enough to have a sugary snack and drink, judging by all the litter strewn around the place. To cap it all off there were a couple of people dragging their two children around the car park in one of those four wheeled festival shopping trolley things. As if they couldn't walk even that short distance themselves. The children looked about the same age, if not slightly older than my son. Who'd walked all the way up, then back again without much bother, about 4 1/2 miles in total. (Having eaten almost as much as me!) No wonder we have an obesity epidemic, and can't even pick our own fruit and veg.
The state of things makes you want to despair at times.
I'm guessing I know the answer, but what are the average fitness and BMI levels like in Sweden?
