It's not so much that people vote Tory more, but rather that people that used to vote Labour don't vote at all since Labour abandoned them. First-past-the-post

It's not so much that people vote Tory more, but rather that people that used to vote Labour don't vote at all since Labour abandoned them. First-past-the-post will always allow the Tories to win with a minority of the national vote. However, politics do exist beyond elections. Strikes have again become common, which could build up to larger campaigns and even a general strike. The organised working class can force even a Tory government to act or face the beginning of revolution.
