Stop using statistics to try and justify it and spend some time in the communities/jobs that deal with this every single day! You may just change your views.
Aka stop using evidence to inform your decisions, listen to anecdata that confirms your bias instead. Pretty much sums up why we're where we are tbh.
But if that's the route we're going down so be it, here's my anecdata.
I grew up in one of the most deprived areas in the UK, at a time when migration wasn't considered a problem but, single mothers, benefit scroungers (not even slightly ironically) and 'blacks' were to blame for our ills. My family managed to improve our lot and we left that area in my late teens.
I now live somewhere with quite a bit of diversity (including two asylum hotels within 5 miles of my house). I have Ugandan, Indian, Polish, Turkish and German neighbours (that I know of). The local mosque (built only a few years ago) regularly holds community events for everyone to attend, as does the polish club, and both do a huge amount for local charities. We've an interesting selection of shops and cafés including a Polish and Asian supermarket, a Jamaican cafe (that does an unreal jerk chicken baguette), and a brilliant independent jewellery run by a lady from Kuwait.
I've never, not once, had a negative interaction with any migrant in or around my community since I moved here over 10 years ago, and they 100% improve the town and the lives of everyone who lives here.
Contrast that to where I grew up (was back there just a couple of weeks ago for a memorial of a friend who lost their life to drugs). It's still deprived, it's still 90+% white British, and it still has all the same problems, but now the scapegoats are asylum seekers and Muslims. They're the one's to blame for everything wrong with that town, not successive governments ignoring them, not big business closing down local employment, not transport companies reducing services every year and further isolating the community. Nope, it's asylum seekers and Muslims (or all brown people depending on who you ask).
I'm sure if you look at the stats (I know, I know we're not supposed to do that) you'll find that it's the people with the least amount of interaction with migrants who are most vocal in their opposition to them, not those of us who are fortunate enough to have our lives enhanced by sharing cultures with people from across the globe.
