Economically immigrants fill jobs that the resident population cant or will not do (packing and picking at arable farms, cleaning etc). This benefits everybody. Obviously this includes billionaires and I do think that billionaires take much more out of society (and the population ) than they should. But to tackle that you don't change who they exploit (resident population instead of immigrants) you tackle the structural nature of the economy to redistribute their wealth and influence.
To tackle exploitative landlords, you again you change the structure of the system so they cannot exploit both immigrants and the resident population
They also fill jobs that the resident population is not qualified to do, for example 21% of the NHS employees are immigrants
Cultural benefits are so obvious. Exposure to different family structures, exposure to different ideas, exposure to different festivals, exposure to different traditions.
Food is also a thing, don't know what the issue with mentioning food is, please explain?
Oh dear, take a look at the unemployment and underemployment figures, what an utterly bizarre argument to suggest we need an underclass of slave labourer migrants to do the jobs that the existing population deem beneath them and would rather claim benefits instead.
Venture out in the real world and ask the few people who actually ARE looking for permanent full-time work, particularly in entry level and unskilled jobs and they'll tell you how incredibly difficult it is to even get an interview, yet apparently we need hundreds of thousands of immigrants per year "to fill job vacancies"
Ah the old chestnut that "we need 10,000 immigrant NHS workers per year to save the NHS from collapsing"?... Have you ever considered that maybe, just maybe, we might not need those 10,000 migrant NHS workers per year if we didn't have high hundreds of thousands of potential new users of the NHS arriving in the country per year?
You talk about structural change to the system being needed to tackle poverty pay and the extortionate cost of accommodation... yet its entirely due to mass immigration that those issues exist in the first place, mass immigration is far and away the single biggest factor that has enabled the value of labour to be massively eroded and the demand for and cost of accommodation to be massively inflated.
Your position on cultural benefits seems vague at best, I fail to see how any of those things you've mentioned enhance the country socially or culturally and they're as meaningless and indefinable as the usual nice food argument trotted out by the usual suspects.
