I mean, you're already poorer, given that immigration has depressed wages significantly. Post-Brexit, EU immigration was only replaced by non-EU immigration which has a higher tolerance for lower wages and poorer living conditions. Something that I got to see firsthand a couple of weeks back.
Immigration is thought to have a small negative impact on the wages of low skilled workers, but is probably financially beneficial for those further up the payscale.

Yes, in fact this was how Brexit was sold to many south Asian voters: your family will have an easier time moving to the UK.
