Nope, it doesnt matter where do you live and what you got. Everything that you earn you can still save it no matter how much it is. It just depends on your willing and what do you want to achieve and make target how month or years do you want to get it with your saving
This is only true up to a certain point. Some families can't have the luxury of having any savings, it happens a lot and you don't even need to go as far as third world countries, in any country that's being hit by the economic crisis and doesn't belong to a rich neighborhood you can see this phenomena happening where all wages go to basic expenses, therefore its mission impossible to have any relevant savings.
Yes minim wages are always below inflation levels, how useful they are in reality lol
