and when the gold rush is over, the shovel seller also goes out of business. Therefore, the shovel seller ought to sell their business _before_ the gold rush is over! Or find another use for shovels - unfortunately, i don't think there's much use for shovels outside of shovelling gold.
Tell that to Levi's, Wells Fargo, American Express, Armour Meatpacking, Studebaker motors, Ghirardelli chocolates, and Mark Twain, all of which got their start in the California gold rush.
