Well I cannot name billioners but I can name many that turned what I consider rich with respect of their workers. Most people are slaves for their own choice. Being involved in a free life is not easy and for many is too much to handle. Let give those that start businesses the consideration they deserve. I can testify myself, due to the fact that I was an entrepreneur for my entire life, that you can even carry someone in a management position and give them money and power. Some will just drop out and tumble down exactly in the same place where you found them. I made this error many times. Now I understand why some people are enslaved and always poor no matter how much help they receive. In a slave master relation two people decide it's ok.
