There is also the fact that if we continually try to tell those who are net contributors that actually they shouldn't have access to things that should be universal services - which they fund for everyone else - like childcare funding or as many now suggest also disability support or state pensions - then we further increase the divisions in society the social contract is completely destroyed. I have never met someone who pays lots of tax who objects to funding these services for others, but do know lots of others who agree with me that it would be completely unreasonable for us to fund them for everyone else then not be allowed to use them ourselves should we need them. That is a step too far.
Cynically, the fastest way to undermine and destroy any system is to means-test it. Initially lots of naive people think it's a great idea, because why should someone who earns more than them (shock horror) receive a penny (neglecting of course that these services only exist for anyone because such people fund them)? Then, obviously, the threshold is never raised, fiscal drag kicks in, and before you know it, it comes back to bite them and they're all shocked apparently because "it was never meant to mean people like us were excluded!" 🤦🏻♀️😆🙄
Every time it is the same. If you want to effectively eliminate a service entirely the first step is to undermine universal provision, then gradually the threshold will be lowered in real terms (in terms of means-testing) or raised (in terms of criteria-based entitlements) until the service is effectively non-existent for almost everyone.
With this slow erosion you can take the public along, stirring up resentment against those who still receive it and using that as an excuse to further adjust the threshold until you've pretty got rid of the pesky demands from citizens to receive services in return for their tax money. It's so obvious that I'm astonished how many people seem to be obtuse about it even though we've seen the tactic play out in front of our eyes in various areas of public life, in an unusually compressed time period of 15 years, yet gullible people still seem oblivious to the motivations and are happy to get involved with the spite against anybody who earns just slightly more than they do.
There is a reason that in other, more civilised countries with effective public services nobody is suggesting that pensions, childcare funding, disability provision etc should be means-tested. I even saw recently - disgustingly - a suggestion that SEN provision for disabled children in schools should be means tested!
I think economics should be a compulsory core subject at school.
