"salt of the earth"? You mean "common."
In interests of fairness... Glasgow and Edinburgh are both great cities, not as different as chalk and cheese but with enough differences to make them both great places. Visitors to Glasgow may have to look a little harder to find its good points compared to Edinburgh's immediate visual impact, and social inequality may be more apparent in the city centre than in Edinburgh's but it's still well worth spending time in. The fact that Glasgow's pleasures take a little more effort to find probably makes them more satisfying.
