Where your money is secretly rich

Your money has a passport, and it's worth different amounts depending on where it lands. Not slightly different. Absurdly different.

The cleanest way to see it is the burger. The same $10 buys nearly five Big Macs in South Africa and fewer than two in Switzerland. Six of the ten cheapest Big Macs on Earth are in Asia; Switzerland's is 38 percent dearer than America's, the highest premium among 54 countries tracked.

Economists have a duller name for this — purchasing power parity — and a sharper metric buried inside World Bank data: the price level ratio, which tells you what a dollar actually buys on the ground. Vietnam's sits around 0.30 against the United States, meaning the same basket of goods and services costs roughly 30 cents on the dollar.

Read that as a plain sentence: there are functioning, beautiful, fast-wifi countries where existence is 70 percent off.

The arithmetic that makes people quit their leases

This is why geoarbitrage went from finance-blog jargon to a life strategy. Earn in a strong-currency job, spend in a low-price-level country, and the gap becomes your savings rate.

The numbers are genuinely startling. A remote worker keeping a US salary while living in Chiang Mai on about $1,300 a month can hit an 84 percent savings rate; the extra $32,400 a year, compounding at 7 percent, grows to over $450,000 in a decade. A software engineer clearing $78,000 after tax saves maybe $33,000 a year in New York and $66,000 in Thailand — double, for the same job.

Realistic comfortable monthly budgets for one person, from 2026 cost surveys:

In Da Nang, a modern one-bedroom near the beach runs $400-550 and a street-food lunch $1.50; private hospital visits cost $20-40. In the Philippines, $1,500 a month buys what a mid-tier US city charges $4,500 for. A dental cleaning in Thailand: $25.

For retirees the math is even more pointed: the average US Social Security check, about $2,000 a month, barely covers rent in many American cities but funds a comfortable couple's life, rent included, in Ecuador, Colombia, Vietnam or Cambodia.

If your reaction is “that can't be real,” good. Hold that feeling, because the next two sections are about the ways it's real and the ways it isn't.

Trap 1: you probably won't get local prices

Here's what the YouTube thumbnails leave out. The advertised paradise budget assumes local prices, and short-term visitors mostly don't get them. One Canadian writer who tried trading Toronto rent for São Paulo ended up on Airbnb paying more than double the neighbourhood's average rent, “not far off from the typical cost of a Toronto apartment.” The markup is systematic: in Mexico City, the median one-bedroom Airbnb runs about 66 percent above average local rent.

The $500-a-month luxury life you've seen advertised is usually describing the rent line of someone with a year-long local lease, a local SIM and local shopping habits. Real comfortable budgets start around $1,000 in even the cheapest hubs — before you add flights home, visa runs ($480-720 a year in Vietnam, which still has no nomad visa), international health insurance at $200-400 a month, and the productivity tax of moving constantly.

The arbitrage is real. The influencer version of it is a rent line cosplaying as a budget.

Trap 2: your cheap paradise is someone's unaffordable hometown

Now the part this genre of article always skips, and shouldn't.

That “bargain” €1,500 Lisbon apartment is roughly two months of the Portuguese minimum wage, which stood near €760 while average rents hit €1,500. A landlord choosing between €600 a month from a local family and €2,000-3,000 from Airbnb makes the obvious economic choice, with devastating social cost. Parts of central Lisbon are now estimated at over 68 percent short-term rentals. The €0.60 bica became a €2.50 “authentic Portuguese espresso experience” because the market repriced to American budgets, not Portuguese salaries.

Mexico City ran the same script: average rent for a three-bedroom near triple the average local monthly wage of about $450, a third of residents forced to move during the pandemic, evictions up 27 percent in a year. Local activists, notably, mostly don't blame individual nomads; they blame absent tenant protections and a market that privileges whoever shows up with the strongest currency.

Both things are true: the individual remote worker isn't a villain, and the aggregate effect is exactly the affordability crisis they left home to escape, exported.

The skill underneath all of this is price literacy

Strip away the palm trees and this whole subject is one skill: knowing what things should cost, everywhere. The person who gets fleeced abroad and the person who thrives abroad have the same salary. What differs is calibration: one of them knows the taxi is 4x the local rate, that the expat price for that apartment has a Portuguese price hiding under it, that $2.47 is a normal Big Mac in Indonesia and $6.12 is not.

Most people's price instincts fail within their own zip code, let alone across a border. Test yourself honestly: what does a one-bedroom rent for in Hanoi? A doctor's visit in Bangkok? A coffee in Lisbon, 2015 versus now? If you winced, that's the gap.
