I agree with you broadly, but I'm not sure about the "deliberate" underfunding by somebody/thing, in the sense that it's a plan. As far as workers are concerned, I think that we have been involved in a race to the bottom for sometime. Just too many low-wage jobs, and nowhere near enough tax being collected to fund the population's needs. There was a thread a few days ago, - I think it was something like 1 in 5 workers on or below the min wage? - (sorry if that's a TAAT!)
"There were 54 million adults in the UK in 2014/15, but just 31 million - or 56 per cent - of those paid income tax, according to analysis by think tank the Institute for Fiscal Studies (IFS)"
The IFS figures include people whose earnings are too low for tax, the unemployed, and retired. That's a lot of people.
As regards the scapecoating of new arrivals, it's really not pleasant, but also not hard to understand. There's been no point in history when having an ever increasing supply of cheap labour has benefited anyone other than the bosses. Wages will always go down/stagnate if there are lots of people after a few jobs. Thinking particularly of the Valleys, I remember my history lessons covering the Potato Famine in Ireland. A truely awful time - lots of people left, with many coming to Wales to work in the mines. Did the owners welcome them, pay good wages? Did they bollocks. It drove wages down for everyone, and even got to the point where some mine owners were paying their workers with tokens, which could only be exchanged for food in the shops which the mine owners ran. It was probably the nearest to slavery that the UK got.
Sorry for the digression, but I really don't think the overall attitude of many employees has really changed. It's much more civilised now, but it still comes down to "What's the least I can pay".
