Indigo ...the number of Eastern Europeans in many places have gone from pretty much Nill to xx and people notice people talking in different languages in areas where that was not so common.
This is a marked change from previous waves of European migration to the UK such as from Italy, Portugal and Spain. This, sadly gets many people's back up. Why? Because it's change, change form what people are familiar with and know how to navigate and in a sense xenophobia, the fear of strangers.
This doesn't help address the actual issues at hand, just writing people off as xenophobic and ignoring legitimate (if sometimes misguided) concerns.
I grew up in a multicultural area, had BME friends, didn't really "see" race or nationality (aside from subconcious biases I presume), very liberal lefty type unbringing, and was shocked on moving elsewhere and discovering people actually expressing racist views.
However, when there was a surge of Eastern European immigration to this town, it was obvious, and the impact I personally noticed was on housing - it was already tight but became virtually impossible. Really was an obvious drop in the number of places to rent (especially in shared houses as I was at the time). Bearing in mind I experienced homelessness during this time, it did grate somewhat. There was also an impact on the area I worked in (care) - the care homes locally were full of Eastern European staff and the managers preferred them over qualified British staff who actually gave a shit about the job, because they were young and up for working 60hr weeks for a couple of years (oh, only British people are so lazy for only wanting to work 40hrs, I suppose , although some of the EE staff were so lazy they were at work long hours but avoiding doing as much work as possible). A lot going on there, not least the fact that care was/is so low paid I presume they started hiring from elsewhere as they couldn't get the staff, but it seemed to have gone way too far.
It's not "change" bothering a lot of people, it's the negative effect of their lives that no-one seems to give a shit about. I didn't dislike any of my colleagues for not being British, couldn't give a monkeys about that in itself. But I did care that I went through homelessess and some extremely dodgy living situations, and that I struggled to find work. (And that unsuitable people were getting jobs as carers, when all they wanted was a job in UK.)
But no-one seems to want to address these things. I was a Remain voter, btw, but it boils my piss that others dismiss people's struggles as xenophobic because they don't fit a nice simple black-and-white narrative.
