It depends on how you want to define the middle class.<p>Some people define it via income characteristics. So a college graduate, with no house or car, can be middle class if they land a good job.<p>Some people define it via wealth, so a retiree with no income can be middle class if they own their own home, and have a decent amount of savings.<p>Some people use the &#x27;classical&#x27; (ala Marx) definition, in which the middle class are the socio-economic group that can buy the labour of working class, but typically work along-side them. For example, a mom-and-pop shop would have middle class owners, and working class employees.
