Scotland gets more representation in Westminster per head of population than England or Wales.
The way the national money is divided up is also disproportionate. With the "Scottish" oil that may be a way of compensation. A bizarre rationale but there it is.

Now what would the Welsh think of Birmingham getting its water? Or those in Gloucestershire having water carried across its land and roads closed for a duration and no recompense? Just to feed London's voracious appetite for growth. Using a restored canal to ferry water would be some recompense but do they consider it? Lip service is all we get. A long linear reservoir is what they would get!

For the common good? Rarely.

Scotland is not the only enclave to suffer form metrocentricity.
