Just wanted to add to the discussion that no one should be apologetic about his or her earning potential. No one should be embarrassed or feel out of place if they make $10k or $100k or $1M per month, and people making <$1k per month shouldn't be discouraged if others are making more than them at the moment (remember that the majority of the billions of people in the world are living in extreme poverty). Just be grateful for what you have and keep on keeping on. I'm not sure how being a digital nomad became synonymous with the backpacking/hostel lifestyle to begin with, but there are probably a few different reasons for that.
As this community grows and matures and the "younguns" get more experience under their proverbial belts and start growing their businesses, hopefully everyone starts earning more money. There's definitely enough to go around for people who work on the internet. Just because you're living on a budget, doesn't mean that you can't dream big and keep earning/saving more. Just because you live outside your home country, doesn't mean you have to relegate yourself to living on a shoestring. Many people start off that way whether they are starting a career out of high school, taking an entry level corporate job out of college or leaving a job to freelance or be location-independent.
Short story: I studied abroad in college a few times and was counting pennies the entire time. I then moved back abroad after grad school and budgeted absolutely every expense down to the $4 per week I spent on gas for my 4x4. I waited tables, bar tended, taught surf lessons and worked in real estate. I hustled so that I could keep living in Costa Rica. That was over 11 years ago for me and fortunately I was able to advance my career and significantly elevate my standard of living in the process. Everyone starts somewhere. I imagine almost all of us know what it's like to be on an extreme budget, but with goal setting and hard work, your earning potential is virtually infinite (just like your creativity). Instead of marveling at people who currently earn over $10k/month, remember YOU can do it too. It should be a realistic goal for anyone who sets an intention to make that much then goes for it!
With the freedom this lifestyle offers, we are the only ones who can hold ourselves back (not a fixed salary, boss, dead end job or glass ceiling). The world is your oyster guys!
