The Bible does not speak against being rich. Abraham, too, was a rich man.
Where some rich (and poor, and everyone in between) go haywire is when they put acquisition of wealth above acquisition of repentance and godliness. The Bible does not say, "Money is the rood of all evil," as some suppose, but rather "The love of money is the root of all evil." (I Timothy 6:10).
If one makes a god of money (or sports, or anything), then God is rejected, and much evil results.
