Chinese products aren't that cheap.
Everyone I've heard complain about the prices has either never tried to actually order anything from a non-Chinese company or they have a tiny order volume that is unprofitable for private factories to tool up for (which appears to be the case in the video).
Here's a random example:
This product is made in China by a company that is an extension of the People's Liberation Army (and therefore gets enormous amounts of state subsidies):

It's 99.99% Made in America competitor (only foreign part is a LED crystal from Germany) is only 38% more expensive:

and they're still in the process of paying off the factory (Holosun got free factories courtesy of the CCP) and plan to lower the price once they can afford to.
American companies can compete on a level playing field.
Holosuns are also poor quality compared to their competitors but their fanboys dismiss all complaints because of their low price. Their dot blooms way worse than competitors (causing many people to think they have astigmatism) and they blatantly lie about their battery life.
