I went on a mission trip to Mexico once. And I'll never forget an experience I had there. While we were outside doing activities, one of the missionary's neighbors became drunkenly belligerent and started threatening the missionary's life. Now the missionary didn't take this as harmless. (I guess he knew who he was dealing with. (It's not uncommon to see people in the Yucatan go down the streets on a horse, carrying rifles or swords draped across their backs.) Anyway, after the altercation, I asked the missionary how he was able to have as much courage as he did and not fear death, and he told me that before he ever arrived in Mexico (and he had been there for over 50 years) that he counted himself as dead long before he ever stepped foot in the country.
That was so powerful on a couple levels for me, and I'll never forget it. As it pertains to business, wealth, and ethics..I would say that if a person hasn't become settled in the fact that he/she will know how to handle large sums of money without falling into temptation, then they probably shouldn't be seeking that kind of cash. Because more than likely they will stumble or get into major trouble. As for the other things, it doesn't bother me to know that some ventures will end up having to shut down due to the world system's regulations on believers' ethics. The way I look at it is this: God is the Creator of all things. The Bible goes on to say that He gives knowledge for witty inventions (KJV). It does not hurt God's resources one bit if a Hobby Lobby or a family's bakery store closes its doors. He owns the cattle on a thousand hills. The earth is His and everything in it. He'll just give the same people (who love Him) the inspiration to start something else that will be profitable.
