Iranians can sometimes be surprisingly pale while isrealis can sometimes be surprisingly dark, there are of course the mizrahi jews but the beta isreal population are straight up black. I don’t think it’s as much a race thing as it is a western aligned vs non-western aligned thing. Other western aligned countries like Taiwan also get overwhelmingly positive media coverage despite not being white. The fact that Iranians are Muslims also contribute a lot to their bad media image. Lots of isrealis could fit in with Iranians without any problem looks wise but absolutely not culture wise.
It’s true that this is very bad news for the moneyed class. But it can simultaneously also be bad news for normal people. A higher ratio of pensioners to tax payers will raise taxes for everyone which is a bad thing, to everyone. This is true for any economic system I can imagine. Even in an economic system without money having a high ratio of pensioners means a larger portion of working people have to be dedicated to taking care of the elderly which means less medical workers, less farmers, less social workers helping the non-pensioners etc, meaning worse living standards for the population.
Even in your preferred dream society and economic system (which I don’t know about) I can’t see an aging population being a good thing. If you have a suggestion for how it could be a good thing please enlighten me. And before you say we can just tax the rich to pay for pensions. You could also tax the rich to pay for better healthcare, which would be preferably for us non-pensioners would it not?
