There's really no need to refute a statement which goes directly against sustained personal observation, especially when it is made without producing any actual evidence.

Obviously not everyone earns the same, then again local people tend to have more money than even wealthy foreigners at the high end, and at the low end at least tend to benefit from free housing, familial support networks, and do not have to fund international travel to maintain ties to home.

Furthermore, downvoting because you don't agree with someone is considered bad form.
