Ozi, most people work really hard but they can't afford private education for their kids or private health care to jump the queues. However you're not being stopped from doing this so what is your problem.
You pay taxes just like everyone else, except the rich and multinational companies, but it only pays for a certain standard of service for everyone. If you believe the service should be excellent for everyone then that requires more taxes which people are unwilling to pay.
In the UK power prices have gone up at a ridiculous rate and are far higher than they were when the companies were in state hands. There are many reasons but one of them is that they have duty to their shareholders, enshrined in law, to do right by them before doing right by their 63 million customers. They have also pretty much formed a cartel. The railway network which was privatised is pretty much paid for by the government because the private companies were appalling bad and demanded money from the government otherwise they would stopped providing services. This is fine for them but very bad for the economy if people can't get to work.
For the UK contrary to media rubbish, the government figures show that immigration is a net benefit to the UK, that welfare fraud accounts for less than 1% compared to a massive deficit in tax revenue. Most people are on PAYE so don't have the luxury of fiddling their taxes like many of the better off clearly do - most of them are not breaking the law but are aggressively minimising their tax bill. The UK Inland Revenue has several thousand names from a bank in Switzerland where UK citizens were hiding their wealth - there has been 1 prosecution!
People who don't play a sport are armchair experts if they comment on that sport but I don't think that phrase translates too well in other walks of life. Are you a professional economist and even if you are what's that saying "Put 10 economists in a room and you'll get 11 opinions"?
However I do sympathise with you over the unfairness of benefits. I've paid in a lot more than most people but ultimately through various reasons I'll get much less out and as ordinary person that kind of pisses me off. If you have a small amount of savings you get no benefits which surely does discriminate of people who have attempted to look after themselves - this is where government takes advantage.
