问题: Why do people buy a lot of household appliances?

These devices are very popular now because they mean less to worry about at home. As people work longer and harder, they want to manage their homes more efficiently.

I think it has to do with making our house smarter. The less housework we have to do, the more we can relax and spend that time doing what we want instead.
