Tbf, even he thinks something needs to be done about those coming in through non legal channels, eg, on boats, or those overstaying, etc.
As he notes, it's never good to appear to treat one group more favourably than another, as it leads to resentment, as we're now seeing.
We've been here ~20 years now, and apart from the 7 months it took him to find work when we first got here (which we funded through savings), he has always been in work.
He's pretty healthy, so has only used the NHS once, for an emergency surgery after he'd been living here for about 7 years.
Once he woke up from the surgery, someone came with forms as they wanted to check whether he was entitled to treatment or would have to pay, so they took employment details, etc, and checked it out before he was discharged.
Since getting a better paid job, he's had private healthcare, so doesn't really use the NHS for anything. He definitely feels his tax could be spent more wisely, and fears governments are not encouraging higher earners to want to stay. The incentives to take risks, start a business, etc, are slowly being eroded in more punitive tax rules.
