The whole applying to their families doesn't work when there have been hundreds of changes to immigration law over the last couple of decades, which means it's very likely they wouldn't have been able to migrate under our current laws anyways, nevermind the mess Reform says they want. That ladder was pulled up, tossed away, and been replaced ages ago.
I mean, the legal way I immigrated was no longer legal within about 4 years after I did so. Literally every step from the way I arrived to all the visas, to when I did the testing (I had indefinite leave to remain before testing came in), it's all been changed over the years.
People on indefinite leave to remain/settled status have been fucked over and had to jump through hoops to regain rights already tested, background checked, and paid for before. Some of the people named were involved in previous ones like the biometric residency permit and the more recent digital version. This constant changing and having to prove yourself again and again has happened to a lot of us. Every new application or requirement to fulfil is a whole new set of fees, documents for the private partners to process....
I'd more question why many of the wealthy - whoever their parents are - like this rhetoric even though they get the most benefit from all this. We can make all the claims about them individuals, but when most of them have been involved in the hundreds of changes, most of which were claimed at the time to be about reducing, they brought in private companies into the immigration process, we should ask why they benefit from this rhetoric and their previous action. We have so many gangs bringing in people illegally who get caught, deported, and bringing them back to 'pay off debts' that our government is doing far too little about.
I wouldn't be focused on their words, I wouldn't be focusing on who their parents are or the colour of their skin, focus on the impact of what they've done already and follow on who is profiting for our immigration system being an ever changing, ever growing mess. And yes, migrants and our children are quite capable of having harsh opinions on that even if we couldn't meet the current or any dreamed up requirements.
