My point exactly, it's just exact replication of the past western immigration problems. There is absolutely nothing making the immigrants assimilate except for a suggestion to do so, and if they don't, oh well, your problem.
Why would they do that? I'd suspect those are outright economic immigrants and have absolutely zero interest in Rwanda, which is why no economic migrants want to go there.
As many American, Japanese and Chinese tourists demonstrate, Philippines apparently are a nice enough place to be in if you have money.
Well, Mizrahi Jews have assimilated pretty well in Israel in spite of their low socioeconomic status, no? Ditto for Mexicans here in the US. Here, the common Israeli Jewish culture will serve as an assimilating glue for them.
The logic in having them go to Rwanda is that the very same purchasing power goes a lot further there since stuff is much cheaper there. So, if you're a Filipino and you've saved up a lot of money by working in Israel for 20 years or whatever, you could subsequently enjoy a very nice retirement in Rwanda at five-star hotels and whatnot.
