Dey took err jawbs i saw it in da documantery (tbh was so surprised someone they interviewed said a word as big as documentary...)
Thing is when I look on indeed, reed etc, there seems to be no end of low skilled jobs around, in fairness likely not enough for every single unemployed person, but the nature of the economy means you'll never have 100% employment....but when it's the same people with no job for decades..they're the problem. If a Polish guy with a reasonable but not fantastic grip of English keeps getting jobs you don't...you need to look in the mirror. Work ethic is a big thing, yeah of course it's a generalisation but I've had actual conversations with either jobless or dead end min wage workers who've said things like "Well I ain't doing that, says you got to start at 5am? **** that. Gotta do weekend shifts? **** that I ain't doing weekends who'd do that?" etc.
The only caveat I'd have is that again obviously I can only speak from what I see where I live in Nottingham, but when foreign workers set up their own businesses, mainly say cafe's, restaurants, hair dressers, they have a very high tendency to exclusively have those from their community employed. This is especially an issue with Chinese businesses in my area due to the high number of Chinese students(lol non-EU), where more and more signs are being put up only in Chinese and apparently (as in asking Chinese folks to translate) many are job advertisements, others are menus with no English which obviously doesn't help integration.
In general though, better yourself, we need as many young workers as possible, especially if they end up going home when they're older, to pay for the costs of an aging population.
