In my country, what causes economy problems is the rise of petroleum, fuel and other gaseous substance, once the price of these chemicals go up, then the economy is in doom where it's hard to solve the problems, everything rises in price even a product that doesn't use fuel to function.
The amazing part is that, the government officials never care much about this but always come up with fail projects to lift this matter.
While rising prices are certainly a natural occurrence, they can sometimes be a significant problem for lower- and middle-class people. Given that everyone's economic circumstances are different, some are prepared for price increases and don't think much about them because they can afford them. On the other hand, those in the lower-middle class may not be prepared and may protest to the government, but this often doesn't lead to any improvement.
