What was the direct factor that led to the demise of the Ming Dynasty?

The Ming Dynasty perished because of the decrease of silver input. Western scholars put forward the view that a large amount of foreign silver was imported into China in the late Ming Dynasty, which led to inflation. Later, it was unprofitable to produce silver, which led to a decrease in the amount of silver mined, a decrease in the amount of silver imported from China, and more private silver was hoarded, leading to deflation. As the previous inflation has occurred, the end result is expensive materials and lack of silver, leading to economic collapse. This view is wrong. Why? In today's words, the reduction of silver investment means that the money supply in the market is insufficient, which leads to the decline of prices. However, in the late Ming Dynasty, the circulation of silver in the market decreased, but the price rose, because there was too much silver in the early stage, which led to the high price in the early stage. Don't worry about this, but why does the circulation of silver decrease and the price rise instead of falling? This is due to structural inflation, that is, the decrease in the output of basic commodity-grain leads to the increase in food prices, which in turn drives the prices of other commodities to rise, so the fundamental problem is still the food problem, not the silver problem. As for the reduction of silver, the government has no money to buy food to help the victims, which is a joke. At the end of the Ming dynasty, even if you have more money, can you buy food? Therefore, the demise of the Ming Dynasty has nothing to do with the amount of silver imported.
