During 2010, two of the richest people in the world (Warren Buffett and Bill Gates) initiated a movement in which billionaires would commit to giving at least one-half of their wealth to charity or to serve the public good. Is this a good idea or is it merely a way to avoid to keep the government from taking their wealth in taxes? Should this idea be extended to include people of lesser wealth?

Should the estate tax be abolished forever, permitting families of successful, wealthy individuals to retain their wealth without government interference? Why or why not?
