Ok, so I live in probably one of the areas most affected by this. I am also married to a migrant, but not recent. Around our area we have many HMO's and also unofficial HMO's, the houses opposite us were re-let recently, they are 2 and 3 bed and now house 10 people collectively. My neighbours next door in a 2 bed have a child and also a lodger as the rent is high (they are paying well over double what we pay as mortgage for same size property).
The schools in the city I live are almost all full and it is very difficult to move schools if you move to a different area. Many of the classes at my son's school are over the 30 in infants and well over in juniors. It has also expanded twice in recent years.
My DH works for a well known national firm whose shops I am willing to bet most of you have frequented. He works in the logistics side. Over the years since he started the proportion of migrants as workers has grown but also the benefits they used to get and the actual contracts have been downgraded hugely. My DH is lucky, he is on an old contract which means he still gets a decent wage. But he feels horribly guilty about coming out with nearly £400 more in his wage packet than his friend from Eastern Europe for the same work. The terms of the contract often mean that some of the workforce (migrants) come out with so little that they are having to go to food banks. Just this year they lost the small bonus that they did get and the day off for Christmas shopping that they historically have had since the firm was founded.
Just the other day a Polish colleague was complaining to DH that she couldn't get a doctors appointment.
Many of the migrants DH works with have already returned because life isn't that good here and they can see very little way of progressing and moving up the ladder. Our neighbours (Polish) would desparately love to buy a house, but it's out of their reach.
And if we take more and more and more people? Can we tell them that yes, the services will be there for you, no you will not have to use foodbanks, yes you could hope to buy a house, no you won't have to live in a house with 8 others that was built for a couple and child, yes there is a primary school place for your child, you will be seen by a doctor when you need it.
Sadly I don't think around here we can answer positively any of those questions.
