The main appeal of Farage/Reform is he gives simple answers to complex problems:
Housing shortage= too many immigrants whereas it's actually too little investment in affordable housing and all that entails eg planning, land costs, profits for building companies, shortage of skilled workers etc etc
Problems getting NHS treatment = too many immigrants whereas 20% of the NHS staff are immmigrants which is far less than the proportion using the service, too many people with co-morbities, an ageing population, a lack of investment etc etc
Dreadful social care= too many immigrants whereas poorly paid immigrants are caring for a great many people, lack of investment, profits made by privatisation of services
Lack of school places - too many immigrants whereas there's actually NOT an overall shortage of school places, we have schools that are underfunded because they have insufficient pupils!
Lack of economic growth= spending too much money on immigrants whereas we have a insufficient labour to increase our economy and are relying on immigrants to keep so many of services running.
I could go on, but basically if you look at Reform's "pledges" it is totally uncosted and I doubt you would find an economist who would validate it. However, it isn't about that is it? It's basically all about immigration, just as UKIP was all about immigration. The simple answer to complex problems, find scapegoats and blame them. This is exactly what Hitler did, he told the German population that all there ills were due to the Jews, got enough to accept that and then made sure anyone else who disagreed was "dealt with".
