here's a simple one for example - some people do not believe in centralisation of power even at the national level let alone at the superstate level.
or some people do not believe in free movement in a superstate where massive inequities between wages and benefits exist. that some people, scoff and sneer as you might, genuinely believe in a nation putting it's own interests and that of it's citizens first.
that some people believe that cheaply importing already skilled labour leads directly to ceasing to train our own youth re: the nhs bursaries are taken away meaning any british youngster who would like to be a nurse, occupational therapist etc finds that now they will need to stump up 27k of fees and 3 years of rent and living expenses whilst being too busy on placements to work directly in order to gain access to in some cases a wage of less than 20k.
that some people note and believe untenable that young people who live in a society that charges them a fortune to qualify even for relatively low paid jobs cannot compete with youngsters living in countries where education is free and the cost of living is low.
that some people have seen wages really drop - forget minimum wage as a decoy look at the fact that people at the lower paid end of the spectrum could once (as i did as a youngster when trying to fund uni or deal with an in between year) increase their earnings by working evening shifts, nights or weekends for which they used to have pay a decent extra incentive. Now they don't have to because there is a labour force willing to work unsocial hours for minimum wage in skilled jobs.
A friend of mine for example sources security guards for various contracts and basically only employs non nationals because they pay minimum wage for a job that people have to pay to gain their own license for (literally they have to do the training and pay the fee themselves - around £300) and they work 12 hour overnight shifts on site. They need their own transport as these sites are all over the place, they are on zero hour contracts and have no fixed hours. That job a decade or two ago would have been a good source of income with premium rates for night shifts - a way of someone willing to work hard to be able to earn a decent wage. Not now. The only people who can afford to do it are those coming from a very different economy and willing to live 5 working adults to a house.
what people seem to fail to realise is how shit things already are at the bottom and how far pay and expectations have already been eroded. this crap of 'minimum wage means it's fine', 'local people are just too lazy/don't want to do these jobs' is nonsense.
FOM is a capitalists wet dream - people voting against it are doing quite the opposite of the 'turkeys voting for christmas' analogy. that in fact is what they were being asked to do.
gosh even if you people haven't done a proper on the ground job in decades you surely did as students and teens?
