I would echo those who have mentioned the cost of even the small amount of illegal migration being a huge factor.
If I remember correctly, Rachel Reeves has suggested there is a £2bn black hole in the economy, to the point where OAPs are losing their winter fuel payments unless they are on Pension credit.
It doesn't end at the housing cost either, it's the use of the NHS, benefits, legal aid for solicitors to argue for permanent status etc.
About a year ago, I had a hospital appointment. I had waited 18 months for this so called "urgent" appointment and it had been cancelled once due to staffing issues.
I got to my appointment ten minutes early because it's polite to do so to allow time to book in etc. My appointment time was 3.15pm.
By 4pm I started to get a little concerned as there was just myself, another lady and a couple in the waiting room. The lady on her own sat next to me and asked what time my appointment was for as she was getting worried about the delay as she had something to attend after her appointment. Her appointment was supposed to have been for 2.45pm with the same consultant.
I politely asked on the desk to be told there was a delay as a patient needed an interpreter and they only had two at the hospital due to illness. I asked why the consultant couldn't just see other ladies while they waited to be told he couldn't.
By 4.30pm, I was starting to think I would have to go home as the clinic shut at 5pm.
A nurse than approached and asked myself and the lady next to me to speak to her in a side room. She told us as we were unaccompanied females the male consultant did not want to see us, did either of us have the option of calling our husbands to attend? I was baffled! I asked her if she was joking, said we had both waited way over our appointment time and this was a farce. After much discussion she agreed to ask a female consultant to see us instead.
As a result, my appointment was rushed, I was treated as out of order as apparently this consultant was meant to finish early and it was a total waste of time.
I ended up contacting PALs who said they had heard similar to me from other ladies about this clinic and others. They asked the lead consultant to call me. She did so and was just rude and flippant. When I said it was ridiculous to expect me to bring DH, and I'm quite able to speak up for myself, she accused me of being "moderately racist". I asked how so and she just said she wouldn't discuss it further.
So after an 18 month wait, and ages waiting at a hospital, 5 minutes in and out and I'm still just as bad off as I was. I went there to have a discussion on my options with an operation which would make my life a lot better but was told there was no funding.
Considering the cost of interpreters to the NHS alone is well into the millions of pounds (according to Google it was £43,095,493 between 2019 and 2020) and remember, they need them in schools, job centres, council offices etc, the costs rack up.
And at a time when Labour is suggesting the way out of a budget black hole is to give some old people the horrible choice of eating or heating people will suggest there are better cuts to be made.
We are facing difficult choices as a country and it will be interesting to see what Kier Starmer does in his first very big test of leading the country.
It's of course not the answer for thugs wanting an excuse to riot and steal stuff to create unrest. But I do believe a dialogue on where our collective money is spent and justification for it needs to happen. We don't have infinite resources.
