I'd rather pay a 200% to someone who is giving back to the community as much as they can, than 50% to some feckless oxygen thief.For those who need it, the system works very well. A Danish ex of mine is long-term sick with mental health issues. She was abandoned by her partner to look after a severely autistic child - oh, he also left her with around £70k of debts. Never let it be said that all ex-servicemen are honourable.
She gets a flat but it's in an area that, until recent redevelopment, would be described as 'lively'. She's also had to convert the front room into her room to give the child his own bedroom. She regularly uses food banks. That all said, the state is providing and there is a structured path for her to get back to work after being signed off. It may only be one or two hours a week long-term, but they work very closely with her. In reality, one/two hours a week is nothing but it's about keeping her engaged with reality and sanity.
But, like you say, the tax burden is horrendous.
