The lower eschalons are concerned with developing their character. Masons are all about building stuff, they built many of the buildings and roads that make up our society.
I have no doubt that many of them are interested in becoming better people. I used to live with and love a man who was a Mason, and he was a really good guy. They are all about "The Light" although , being a 'boys club' a lot of them are very much into treating women like good little wives who take care of the home and cook etc. so from a feminist perspective, they are a little outdated.
The upper eschalons are another story alltogether. They are the Lawyers, the doctors and Presidents, rather than the butchers, the bakers and candlestick makers...and Power corrupts absolutely, so who knows what goes on in those circles?
