Real Purchasing Power (PPP-Adjusted)
The most honest comparison: take each net salary and adjust it for what it can actually buy in the local market. A dollar in South Korea buys more or less stuff than a dollar in Mexico — this table shows the equivalent local purchasing power.
True winner (after cost-of-living): Mexico
On average, 38.2% more real purchasing power across the salary levels compared. Note: this differs from the tax-only winner (South Korea) — once you account for local prices, the picture changes.

This comparison uses national/federal income tax plus social security contributions.
