Traveling the world there are several places where $150 a month is more than the locals make. And even where they aren't, there's things like free-camping, getting a place with several friends together, and so on.

Even in a first world country with $1500+/month average wage, getting by on holidays with €150-€200 is something a lot of younger friends do, if anything because they have to (not many saved from poorly paying and scarce regular jobs anyway). If you bunch up a few together, or just go camping, it's quite cheap.

The world or south east Asia? Even Eastern Europe is going to be tough on $5/day.

Asia, Africa, Latin America, even parts of Europe.

For comparison, in Greece there are tons of young (and older) people actually working full time for ~ €400/month.

(Before the crisis, in say 2006-2010 those were called the "€700 euro generation" for making around that amount per month, then considered very low).

Here's a similar case in Spain: "“We’re not mileuristas. We are just poor. I wish I could earn €1,000, but my generation is earning between €700 and €800 a month,” he says, adding that he personally takes home around €450 a month for a 20-hour week, and describes himself as underemployed."
