Never said they didn't work. Implied that just not hard at making money. There's no such thing imo as being concerned about you or me or them. It's all about a vision about the future. I'm sure your ancestors didn't get injured in military service because they were worried about themselves. Probably wanted you to live in a better place. Just so happens that the best way to make sure you live a happier life down the line is not to fight in wars, but rather to sell weapons to countries fighting in wars.
Or get the family focused on medicine, pharmaceuticals, or technology.
