Dunno about Alaska or Montana, but in most (if not all) states it is legal to purchase a gun... states differ on their waiting periods and requirements for ownership, but generally criminals and mentally ill people aren't permitted them (there are loopholes of course as in most laws) and most states have a waiting period so you don't go shoot your wife who's in bed with her lover out of anger -- you have to wait 30 days to shoot her!

Everyone can apply for a concealed weapons permit; approval of the application is another matter entirely. But again this varies from state to state.

Cars: I guess it depends on what you mean by "next to nothing". We recently moved from the US to Australia. In the US we had bought a late-model used Hyundai Elantra with plenty of warranty left for about $8500 with CD player, power windows and doors, keyless entry, and automatic transmission. In Australia we paid $14K for a 2004 Hyundai Getz with power windows and doors, CD player, automatic transmission, and plenty of warranty (no keyless entry tho). it's a smaller car, and sort of like a wheelbarrow, for twice the money.

When you own land, you own it... what do you mean by "quasi-communist stuff"? How can you only partially own a piece of land? Unless you're still paying for it from the bank, then the bank technically owns it, but the assumption is that it's yours, just like a house. Can you be more specific about the context here? I don't really understand the question...

Americans have to pay tax on any income they earn in the US even if they live abroad. I will pay Aussie taxes on my Aussie income, but US taxes on income from investments etc. But the tax system in the US system is so confusing that it's anybody's guess, really...
