because of supply and demand. the supply is far less than the demand for these products, therefore there is huge inflation.
...actually, supply and demand dictates that everything
is cheap (by our standards) in a country where average earnings are small. Suppliers simply won't be able to move their products if they price them too high - that's how supply and demand works.
Inflation shouldn't be a major issue because inflation is caused by loads of people spending loads of money in a short period of time. Can't happen on a large scale in a market where nobody's got that much money in the first place.
Poor countries will experience normal rises and falls in inflation, which they'll control the same way rich countries do: by adjusting their central bank's interest rates. You'll occasionally hear about hyper-inflation problems in poor countries, almost always it's a result of their government just printing money to pay workers or debts (Zimbabwe, post-WWII
germany) which is as sure a way as any to devalue your currency.
Note that we're talking about ordinary products here - food, accommodation, clothing etc that are considered normal by local standards. Luxuries will be treated differently and likely
will be expensive because they're usually incredibly expensive and/or difficult to supply in poor countries. And in some countries, things like internet access fast enough to play online poker without timing out every other hand is considered a luxury.
There endeth my Economics 101 rant for the day. With regard to OP's question sure it might work but are you
really willing to live with the downsides, leave your friends and family, probably learn a whole new language and accept a massive drop in living standards just so that you can sit in front of a computer clicking a mouse all day? I'm thinking probably not or if you are you've probably got some other, much more compelling reason to leave your current country of residence.
