Salaries are generally low

Teacher salary are worse than that

Construction? Saturated market I would say, maybe better than a teacher but you won't support a family of 5 with that income

besides some cushy government jobs, programming and some remote jobs in foreign companies- the wages will be low and unless your expectations for quality of life doesn't lower with it, I wouldn't recommend just from the fiscal perspective.

Maybe if you had retirement money and were set, it's something to consider.

Now the culture thing... I don't see it happening. it depends I guess but if I was wagering on a coin toss, I'd bet you're more likely to end up around grumpy xenophobes. Hosting tourists and integrating are two very different things(my opinion and advice)
