I wouldn't say that. Southern Scotland is an area that has traditionally had very 'working class' industries. I guess it's like Rich said earlier, voting labour as thats the done thing.
Neil P also said that Labour have kept his parents in a job so the MPs are obviously doing right by their constituents there.
In the scheme of things you have to vote for who is going to look after you locally and just hope they can bring local issues to Westminster to make a difference.....
