That's terrible man.
$190/month as a dish washer
$45/month as a waiter (with tips that could reach to 2k if you always work overtime and not complain about the lack of extra pay)
How does a dishwasher make tips?
I made a typo in my above comment. As a dishwasher, you get $450/month - fixed and without tips.
I assume also room and board are "free".
For someone working on a cruise ship to make 2x to 8x that and have a substantial portion of their living expenses covered is not at all "terrible" by their home country's standards, IMO.
For some perspective, in a report from recent (last 2 months) research that I read this morning, the very lowest household income amongst Myanmar migrant workers (largely factory workers) interviewed in Thailand was almost exactly this figure (7kTHB), whereas 2-5x this figure (~20-35kTHB) was common.
Similarly, relocating Chinese villagers I met last month reported being given 290元 (~$42)/head/month + lifetime generous monthly rice/oil allowance + initial bulk hardship payment + free housing when relocated to facilitate a new hydropower project. A family of four Chinese farmers in this situation essentially receive this income forever without the need to work at all.
