i would report anyone I knew was committing benefit fraud. There is only so much money too go around. If people cheat the system if could take money from people who really need it.
That there is "only so much money to go around" is a complete fairy story, though. Money isn't real. The bank can, and does, create as much money as it wants to, and as much money as people are willing to borrow. Because it all, eventually, ends up back in a bank.
The fact that you seem to genuinely believe the people who are cheating the system are taking money from people who need it (or anywhere, really!) shows just how much successive governments have done a number on the general population. The budget of a country is not like the budget of a household. They don't have to rob Peter (nhs) to Pay paul (benefits) until Pauline gives them the twenty quid she owes them (taxes). That idea was literally invented to sell austerity to the turkeys and make them want to vote for Christmas.
As I said in a previous post I don't like people who commit any type of fraud, and I think that's a perfectly valid opinion to have. But can we please stop pretending this country is running the same way as one family household? Where if Dad spends the last £10 in the pub, Mum is short on the shopping? It's not Angela's Ashes. I was sure the coronavirus pandemic would have proved to most people that Mum has a blank chequebook.
AND perhaps the most important point, at least that £10 Dad stole is going straight back into the economy to be circulated again and stimulate growth. We should be far more concerned about rich Uncle Richard who has all of his money stashed under the mattress (and is probably fiddling his taxes too).
