The philosophical justifications sound nice and all.

The thing is that when you have a huge non-citizen percentage of the population that is actively drawing taxpayer money out of the state to the point where the social welfare system is beginning to break down, and you have the working citizens of the country being taxed at 50% or more to support that during an escalating global cost of living crisis, you have effectively destroyed the social contract around citizenship that permits this system to function. For the massive aged population that's drawing retiree benefits, there's at least the justification that they paid into the system during their lifetime, even if the equation that makes the retirement system work increasingly doesn't work anymore.

Now the young people are being told to go die to keep that system alive. I wouldn't be surprised if most don't.
