Lizzie,
       There is very little new in our world, not least the folk music world. Woody Guthrie sang about what he saw as social injustices and Pete seeger sang the Les Rice song castigating the financial world with his "The Banks Are Made of Marble" in the 1950`s. Even contributions from such well respected social commentators as those made not one jot of difference. I think the same will result from a few singers over here expressing their dis-satisfaction. Whether we like it or not, without those greedy, arrogant, adventurous, risking, entrepreneurial, chancers we could all still be living in caves and keeping our modesty with loin cloths. Look around you. For everything you see and enjoy is the result of someone somewhere risking their talents in order to achieve a dream and improve their lot.
