Yeah, ofc. But if you don't find a good job in another country, there is no point to do that. Everything depends on what you are capable of, what sort of job you are looking for.
For example, if I would go to Germany and work there, I would have "similar" salary to what I do have here, in my country and if I exchange it to my currency, it's *4. Then it's a lot, a big difference. But living there on daily basis, won't create a big difference. I am not a type of 'money hungry guy' and I can afford many things, so I prefer to stay here where I am with semi good job and salary (average) :P
I could go 'somewhere' for a year, two, three, then come back and I have money to build my house. Many people do like that. But while I have a 'good' job and I can't complain that much, I won't risk that I lose the job and I fail hard aboard and come back with hand in my ass - many ppl did. If shit happens in future, sure thing, nothing to lose so I can change country :D
