Perhaps. I think it's more about the passport ranking so one can travel and also the salary bump. But even if more of the other government services, try living in a country where if you get into a serious car accident you have to pay cash at the ER before they treat you. Scrambling to find multiple thousands of dollars in cash at 3am sometimes. (This happened to my friend in Kenya)
Im not sure if I can blame people for wanting to have more financial or medical security.
Is it legal to let people suffer or even die at the ER on Kenya if they don’t happen to carry a few k$?
Fair point, just looked it up and it seems to be illegal to do that. But in my experience, many probably still do it, or people don't trust that hospitals will follow the law...it may be more of that latter part, not knowing whether they will or won't ask you for money, or whether they will or won't take your insurance. So I think that uncertainty can mean having to be prepared for it anyway.
I think a very low percentage of migrants do it so that they can get a better passport for traveling. Sure, there are people who do that also.
Fair point. I also think the same group you're talking about is probably not thinking about going back home with just government benefits to sustain them. They probably are more focused on working in countries with higher wages and building big homes back home. I think it tends to be more wage driven than government benefit driven, but I could be wrong.
