Shanghai and London may have similar costs of living after certain factors are accounted for, but that’s a coincidence not a rule. Compare Manchester and London. London has much higher rents and higher prices in shops, bars and restaurants. Everything else is about the same. Ergo, London has a higher cost of living.
