There's also a bunch of lovely people. One of the companies I worked with had a remote office in Romania, and onshored a fair amount of staff, and they were perfectly european culturally.
The counter is obviously there's nothing wrong with Romanians ethnically, but there has been downsides of denying the negative consequences of immigration, which had helped fuel our absolute farce of removing from the union.
With that said, from the little knowledge I have on the issues, many of these issues are the UK shooting itself in the foot, but my point is these are not black and white issues, but rather complex issues that are better fixed for an increasingly stable Europe.
