Good points.
But do you think the homeless are the results of 3rd world immigration? I see a lot of the homeless in SoCal and the majority look like they’re whites.
The US is overwhelmingly importing people from 3rd world countries that will vote Democrat. If anyone believes that California's homelessness problems, for example, are due in large part to Democrat management, then, making certain that Democrats stay in power by importing Democrat voters, could contribute to homelessness.
I don't see the logic in suggesting that 3rd world immigrants are the cause of the types of mental illnesses in American citizens that lead to homelessness. But if tax payer money that is now spent on accommodating foreign refugees, etc..., in large numbers, could temporarily house the otherwise-working American homeless, then yes, you wouldn't see so many tents in SoCal. If we needed more workers there could have been, could still be, government incentives for working Americans to have more children and we could also continue to import 'the cream of the crop' as much as possible immigrant-wise.
There are Black families that have been in the the US for centuries yet, in LA County, which is 8% Black, roughly 34% are homeless. Is it fair to them switching resources to people whose families just entered the US? Black homelessness effects everyone. Latinos/Hispanics are under represented homeless-wise. They're roughly 48% of the population but 36% of the homeless, which could be due to factors like low cost of living, many living in one house, etc... all of which keeps a roof over their heads. Whites are roughly 26% of the population and 25% of the homeless. Homeless Whites may happen to congregate in areas that are closer to where other Whites live, therefore they may be seen more by Whites. The average person sees a small percentage of the homeless in their daily travels.
