Dumping is used to drive competition out of business...like the garment industry, electronics, auto’s etc. It’s working.
In other words, profit-seeking will always create scenarios where monopolies will not last [unless, of course, government establishes the monopoly through policy or the monopoly is a true natural monopoly].
Challenge to protectionists on the board: please provide one instance where a 'dumping' country/company has ever maintained a corner on a market for an item.
Show me where dumping works over the course of a decade or two to drive out local manufacturers, capture the market for a foreign manufacturer who is then able to defend against the next dumper.
I’m open to persuasion, I just don’t have any historic example at hand. Awaiting your enlightenment....
