It’s not a belief, it’s a fact and it’s why we have progressive taxation.
Immigration status is actually taken into account. The Beveridge Report in 1942 specifically mentions UK citizens. It was through numerous EU treaties that extends this to EU citizens as a whole and ILR as we know it today was set up in 2003. Net migration has increased significantly from then and was assumed a low % of migrants would be self-sufficient and net-tax contributors, that’s no longer the case. 1/6 UC claimants being foreign is clearly a big problem. In 2022, payments to foreigners on UC was £6bn, surpassed £10bn in 2024 and projected to be £12bn this year…
With respect, it’s you that was trying to play silly games and ended up looking silly when it become apparent you couldn’t (or wouldn’t) distinguish public services and welfare handouts. The clues are in the names; National Health Service, Personal Independence Payment, Universal Credit.
One final point, if yourself and others articulate “the need” for reform on immigration or welfare and yet, offer no ideas, decry any suggestions made and use straw man arguments or ask stupid questions like ‘why are the elderly/children not classed as “unproductive” and not working age adults?’ At best, you’re playing a fool…
