There are thousands are companies that exist solely as a tax dodge for some other company or in order to prevent paying workers at a different company. Some companies exist to just play games with money on the market, which has at best only very indirect benefit to the society as a whole and has a definite chance of being a harm to society. Some companies exist simply to drain all of the money out of other companies before they go bankrupt.

None of this is illegal, but it's hard to argue a benefit to society in general.
