On Unrestrained Consumption
Our country is in a phase of fast development and people’s consumption level mounts up along with it, too. Although people are wealthier than before, there comes a problem that is worthy of our paying attention to, namely, the problem of unrestrained consumption. It is common to see that what people purchase does not simply meet their basic needs, but surpass them. Especially when it comes to vacations, the phenomenon of unrestrained consumption can be seen anywhere. For example, in the restaurants there are a lot of food left on the table when people leave. Inevitably both individuals and society will be affected greatly by the problem of unrestrained consumption.
Personal unrestrained consumption will not only affect the quality of their own life but affect their family as well. Many ladies are accustomed to comparing their dresses with others so they buy all kinds of fashionable and expensive dresses beyond their needs, which directly indoctrinate their children With wrong consumption concept. As a result, their children are likely to put fashion in the first place, regardless of whether they can afford those expensive things. Besides, we can’t imagine where our society is going if everyone’s aim is to satisfy their endless desire. In order to catch up with the rich who are in possession of villas across the country enjoying a luxurious life, some people try all means to make money and even by illegal means, which surely results in social instability.
As far as I’m concerned, people should control their purchasing desire and consume wisely. What to buy relies on our real needs and our income. If everybody can think about this problem like this, our society will develop peacefully and steadily.
