Cambodia is experiencing a great deal of growth. That would be the best choice. For the single men, they should be warned that the best looking women there are really men. (
Growth is not wealth. Considering the utter shit hole Cambodia was up until... well... it's still a corrupt shit hole... Just slightly less so. Considering the degree of dysfunction and corruption in that place it'd be a fucking miracle not to have growth. Growth could just as well be a measurement of have comparatively bad things used to be. I spent a dinner and a night hanging out with a Swedish hotel owner in Sihanoukville and got the realities of operating businesses there explained to me. It's corrupt beyond belief. Everybody is in cahoots with everybody. Laws only exist to warrant bribes. The rich can do whatever they want. It's a highly dysfunctional kleptocracy.
An important source of the growth is their administration modernising. Ie previously unregistered subsitance farmers are now registered. So nothing has happened. The only difference is that transactions previously off the books is now in the books. This is not real growth. So far they've only picked the low hanging fruit, ie stopped doing retarded shit. Hun Sen still scrapes as much as he can off the top.
I can recommend the highly entertaining and informative Off the Rails in Phnom Penh by Amit Gilboa. It's mostly about the embarrassing shambles of a UN mission when they were put in charge of overseeing Cambodias first democratic election and transition to democracy. Hun Sen simply ignored the election result (he was voted out of power) and stayed anyway. The UN called that a successful mission, packed up and went home. The rest of the world fell silent. And that was 1993. The situation is the same now.
Cambodia is a bad joke of a nation. It's on par with Zimbabwe. If somebody sent me there to make a life for myself I would take it as a personal insult.
