I think you mean work should pay OP.
But think about it, if you are in a flat, claiming benefits, perhaps you could work but you have worked out a way to be ok not working. What choices do you have? What human interaction do you have?
Even employees on minimum wage could, move to the coast, if they wanted. They have the opportunity to upskill, earn more, have more choices.
Being stuck in a property because it's being paid for and to move would be almost impossible because moving areas, finding housing that will set you up as you are in benefits is virtually impossible.
So why would anyone choose this?
Say you are young, just entering the workforce, have got in a rut claiming benefits for mental health, let's say depression, but not "real" depression, just enough to get the benefits depression, what happens then? You see your peers, friends, in a year or two, move on, get better jobs, have relationships, go travelling, have holidays, move away and you are there in the same property, doing the same things, filling out the same forms, no one around in the day because they have stuff to do.
You get little real human contact, never make work friends, never see what is possible because you are mentally trapped.
If you are older, more middle aged, you are not working towards adding a bit, even just a bit, towards your pension, you are likely to either be dependent on a relationship that could fail, being taken advantage of or never really having the attributes to be a desirable partner.
It might seem unfair that people can stay at home, not work, have bills paid, particularly in the winter when you are scrapping the ice off the car or waiting for public transport that's late and having a cross boss. But is it really? 10, 20, 30 years of the same old, same old, stuff on tv, looking for the cheaper foods in the supermarket, not being able to book pricey tickets for a show or an artist.
Is that better because they get their council tax paid for?
There is existence and there is life. And life is outside, it's people, and mess and hard work, and being part of a team, and progressing, and oh loads of other things.
An old school friend of mine has played the system since she was 18, her whole family have, they have definitely had more disposal income in the past than I have but would I have ever swapped, god lord not a chance, she was miserable, the same conversation topics over my annual visits of 30 years, 30 years the same thing. THIRTY YEARS (and counting .....).
Yes work should pay, benefits should be a safety net for those that can't.
There are so many other things that work gives you aside from money. There really is. Stories, complaints, not the same thing for 30 years and counting.
It's nothing, nothing to envy OP. Nothing at all.
