What does "ant tribe" mean?

Ant tribe is not an insect group, but a little-known huge group of "post-80s" or even "post-90s"-"low-income group of college graduates", which refers to college students who can't find a job or have low job income after graduation and live in the urban-rural fringe. The reason why this group is called "ant family" is because this group has many characteristics similar to ants: high IQ, weak quality and gregarious. "Ant tribe" is a typical generalization of "low-income group of college graduates", and it is the fourth vulnerable group after the three vulnerable groups (farmers, migrant workers and laid-off workers): they have received higher education and are mainly engaged in temporary jobs such as insurance sales, electronic equipment sales, advertising marketing and catering services, and some are even unemployed or semi-unemployed; The average monthly income is less than 2,000 yuan, and most of them have no "three insurances" and labor contracts; The average age is between 22 and 29 years old, and 90% belong to the "post-80 s" generation; Mainly living in the urban-rural fringe or suburban rural areas, forming a unique "residential village." Like ants, they are a huge group that is little known.
