Loyalty isn't as esteemed in modern society, which generally values change and transience a lot more. One of my favorite writers, John Updike and one of the most perceptive people I've ever read, wrote that in many ways, laws permitting easier divorces and noncommunication symbolize how our society has come to dismiss permanance as a relic of the past. Honor and loyalty, too, have been lost with it.
That said, if you find other guys with common interests and know them over a couple of years, you'll be surprised how much of a sense of loyalty and brotherhood will develop naturally. I have friends who I would lie for without hesitation, even if they murdered someone, because I know that they would do the same for me.
That's true loyalty.
