I don't see how $2500/mo is cheap by any means.
Ohhh, you can definitely live cheaper. I know of studio apartments for $50/month, there's $1 plates of food available everywhere, I can get a liter of lao khao (horrid Thai whiskey) for I think $4, and so on.
But what's the point of working 80+ hour weeks if you're going to live like you're on welfare? As anyone who's lived here will attest to, you can definitely live on the cheap, but it gets tiresome quite quickly. Then if / when you decide you want a life comparable to the West, cost of living starts going up.
The only real difference here is, instead of living in a condo down town in some metropolis, I get a nice 3bdrm house with large yard. Oh, and I get better customer service than you. As rusvik said, labor here is cheap, so adding extra employees to the payroll is a non-issue. Due to this, everyone has come to expect / demand a much higher level of service than you get in the West, and they won't settle for less.
I have not once bought a piece of furniture or fridge or whatever, without it being delivered hours after leaving the store. If internet goes down, it's one phone call, and within a few hours I have someone at the house up the pole checking it out. Get pissed off one night, punch my laptop and break the screen? No problem, head into town, they'll start working on it straight away, and I'll have a new screen in my laptop within an hour or two. And so on... there's none of this, "let me check the schedule -- I can fit you in next Wednesday between 12 - 4" shit. If a company does that here, they go under.
