As the author says, "Go buy a Schick..." Which is produced by a company that is largely owned by the same investment firms that own Gillette. Nobody gets hurt when you switch your brand loyalty from one brand to another. The same number of razor blades are still being sold and the same people are still profiting off of their sale. Not so sure about that. Schick is produced by Edgewell and Gillette by P & G, which are separate companies.
You can also buy a Bic, made by a French company, Société Bic, which, though public, is still dominated by the family that founded it.
