Kevin O'Leary goes off on MSNBC host, suggests Trump should slap 1000% tariffs on China.

O'Leary says the days of China manipulating the entire world need to end.

"When you shut down a factory, you put thousands, if not tens of thousands of people unemployed in China."

"They take burning torches just like in a Frankenstein movie up to the castle, and that's a bad outcome for the supreme leader."

"Now is the time to settle this because we may not be the largest economy forever, but right now we can squeeze China to comply with the laws and get a level playing field."
