Do Muslims who live in Mecca are more lucky than any other Muslims in the world ?

They are lucky in the sense that they live in Mecca, they have easy access to Medina, they have more people to pray next to in a congregation, but if their hearts and intentions are not clean, then it doesn't matter where they live. A good Muslims who lives a thousand miles away from Mecca is a thousand miles closer to Allah if his heart is clean.
