Precariat

In sociology and economics, the precariat (/prɪˈkɛəriət/) is a neologism for a social class formed by people suffering from precarity, which is a condition of existence without predictability or security, affecting material or psychological welfare. The term is a portmanteau obtained by merging precarious with proletariat.[1] Unlike the proletariat class of industrial workers in the 20th century who lacked their own means of production and hence sold their labour to live, members of the precariat are only partially involved in labour and must undertake extensive "unremunerated activities that are essential if they are to retain access to jobs and to decent earnings". The hallmark of the precariat class is the condition of lack of job security, including intermittent employment or underemployment and the resultant precarious existence.[2] The emergence of this class has been ascribed to the entrenchment of neoliberal capitalism.[3][4] https://en.wikipedia.org/wiki/Precariat

After questioning more than 161,000 people online via a 20-minute survey, the London School of Economics' Mike Savage and the University of Manchester's Fiona Devine have concluded that we should now do away with the out-moded working, middle and upper classes and instead adopt seven new classes. They are in, ahem, descending order: Elite; Established Middle Class; Technical Middle Class, New Affluent Workers; Emergent Service Workers; Traditional Working Class; and Precariat.

I think even middle class people can qualify, esp if they have healthcare problems, etc.
