Yeah I also prefer working with ratio's to determine what's comparatively expensive and cheap. A good example of this would be a Nando's quarter chicken. Let's use the example of an SA salary of R30k net. A Nando's quarter chicken in SA is R32.50. That's 0.11% of net SA salary. In London, a Nando's quarter chicken is GBP 4.35. That means, for the ratio to hold true (so that a quarter chicken in London = 0.11% of your net salary), you would need to earn GBP 3955 per month.
See that makes a lot more sense to me when working it in reverse like that and saying what you should be earning to have the same cost.
Doing it with a figure in hand and then saying it's cheaper or more expensive doesn't really help when the salaries and lifestyles are so different.
Although when it comes to property/rent it's a whole different story where it doesn't work out.
