Sense of justice needed by all in our society

Consider this incident. A group of homebuyers in Changzhou, Jiangsu province, rushed to the office of the real estate company where they had purchased their apartments and smashed whatever they could put their hands on simply because the price of their properties dropped after they bought them.

This followed another case in Hangzhou, capital of East China's Zhejiang province, weeks earlier.

Do these people have the least sense of justice? They know that house prices can rise or fall. It is ridiculous for a buyer to purchase an apartment thinking prices are only going to go up and he or she holds the key to a jackpot.
