"Their children are at schools where multiple languages are spoken. " So what? Does this effect the education of their English speaking child?
"Their GP surgeries are full and they can't get an appointment for weeks." This is not down to EU immigration but to NHS shortages. Immigrants tend not to use the health service much, look up the healthy migrant effect.
"Their wages were being driven down by immigrants who were happy to work for a fraction of their costs and often "off the books".
Then this is ileagal and could have been put a stop to. Nothing to do with the EU, and will continue once we leave.
"Their police forces are struggling with crime and ghettoisation and the costs of interepreters required for people who do not speak any English.!"
Again, unlikely to be the consequence of EU immigration.
In fact what you are stating sounds mostly anecdotal and frankly very little to do with EU immigration. As I said, most people "concerns" aren't valid.
See this is the problem, when people tell you about the Police force being under strain because of immigration, not big spending cuts, when people say the NHS is under pressure because of it, not spending cuts and a lack of GPs, then you start to realise that their blaming of immigrants for societies ills is based on prejudice not fact.
You can't legislate for irrational fears.
