Why don't many things increase in price for decades?

Many things have gone up in price in recent years, but some things have been at this price for decades, and some are even free. Let's talk about what it is today!

The bus cost one yuan for several years! More than 20 years ago, buses in many cities cost one yuan, and now they still cost one yuan. I remember that the air-conditioned bus in Zhengzhou used to be two yuan, but now it has become one yuan.

Newspapers have not raised prices for decades. A newspaper used to cost one yuan, but now many newspapers still cost one yuan. Newspapers are rare, but the price is still one yuan.

We've been drinking for so many years for 3 yuan a bottle. There are still some pure water that has not increased in price.

In addition to goods that do not increase in price, there are some goods that have been decreasing in price, such as cars and home appliances. Especially in the past hundreds of thousands of cars, the configuration is still very poor.

In recent years, there have been more and more cars, with better configurations and lower prices.

In addition to these daily necessities, some places have changed from collecting money to free.

For example, public toilets and parks in cities had to buy tickets to enter parks decades ago. Today's parks are almost free to the public!
