Much of Sweden's military industrial complex is now owned or partly owned by foreign companies. Yes Saab and Bofors made great stuff in the years past, but their future will be reduced to being a partner or sub-contractor to pan-EU or US projects sooner or later. Just as the Swedish army gave up on domestic MBT's and purchased German imports, their AF probably won't see domestic fighter jets beyond the Gripen by 1 generation. As for reacting to external threats, Sweden has none. But this isn't a military forum so I'll stop here.
Monaco barely has 32,000 population, so supporting a socialist system from casino revenue isn't too difficult. If you want to be a citizen there, you'll have to find a way to be a legal resident for at least 10 years before applying for naturalization. If you're looking for inexpensive health care, I'd suggest shopping for health insurance, or checking US government (both state and federal) programs as the US Government is actually the largest insurer in this country. Alternatively you could opt for Canadian residency and apply for benefits there. Many Canadian provinces offer inexpensive investor residency programs that costs much less than other country's.
I believe as a country, we have the economic capability to provide a non-starvation standard of living for all legal residents, assuming that the people are willing to accept government aid. Government assistance is there for those who aren't too lazy to apply for it. Some might think that's a joke, but I personally know someone in Riverside who is in economic hardship (he stay home to provide full time care to his elderly mother) but is too lazy to apply for government aid. No, it's not a pride thing, I've known him for too many years to know exactly how lazy he can be. But my personal belief is that if someone wants to be a bum, that's OK! You shouldn't HAVE to work to eat! Under my tax scheme we'd all pay a Federal flat rate income tax (states retain power to levy state income tax as they see fit), and the government would give everyone couple hundred bucks every month that's tax exempt. If you want to live out of a van, eat Costco hotdogs every day instead of working, and go to government clinics to get pepto bismo, that's fine by me buddy!
