Why didn't the u. s. wants hochiminh to be successful? how does this relate to the domino theory?

because they thought that if they succeed in spreading comunissum, then it would just keep spreading until they hit the US. this is a domino affect, because because of the fall of one thing, more and more governments would keep falling.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.

the noble might have thought that the system was far because they had lot of things and riches and the serf would have thought that the feudal system was un fair because of the way they were treated.
