Part ideology, part incompetence and part corruption.
Open borders is a kind of mad ‘be kind’ ideology that the political classes subscribe to because it makes them feel and sound worldly and cosmopolitan. makes them look like they are outward looking, when really they are thick as mince who have no ideas on how to do the hard work to make the country better, just focus on optics.
And the incompetence part is that low skilled labour costs less than training up your own population. Notice how the benefits bill started 59 balloon when tax credits were introduced and it was about the time immigration started to get out of control.
Our ruling classes have been of a particularly low calibre since 1997. People who rather than growing the skills and income of the nation, decided to import cheap labour and give a bung in the form of unlimited benefits to the locals to keep them quiet. Ever since that time, GDP per capita has been in decline. We bring in low skilled immigrants with huge families that will never earn enough to contribute enough that they pay for themselves. At the same time we have a ballooning welfare bill for the locals.
We used to build stuff to sell. Not just manufacturing, but intellectual property, finance, high value commodities. Thats how you generate wealth. Now this country is a conveyor of second rate universities and bogus colleges pretending to sell an education and selling visas instead, often to ‘mature’ students who bring wife, kids, parents and other elderly relatives and (understandably) use it as a way to get indefinite leave to remain. And there a racket in every sector engaging in import of low skilled labour. The care sector is literally colluding with fake immigration ‘companies’ that sell visas abroad. Thats not a romantic view of the past, just a factual observation.
All of these ‘businesses’ benefiting from open borders are either donors to these corrupt politicians or the politicians are advisors or employed by these companies after m leaving office. These people are ripping us off and laughing at us.
At the same time the asylum system is broken beyond repair. Why? It’s just too ‘ard, innit?
None of that has made the country richer. The myth that uncontrolled immigration is good for the economy is a total lie.
