The great majority of businesses are “unseemly”. The stock market is gambling pure and simple. Some do it with more information and research than others. The professionals do better than the casual for that reason. The State sanctions gambling with lotteries, etc.
And it isn’t the gambling that is unseemly, it is what can surround it. But what surrounds it surrounds everything. The problem isn’t the gambling and the Bible sure takes no stand against it.
I’ve never had a problem with it and don’t get the fuss.
LOL, I always think of the scene in "Trading Places", where the Dukes explain to Eddie Murphy their business, and Eddie responds with, "Sounds to me like you guys a couple of bookies."
