What does it mean when it says revolution by the underclass is inevitable?

When it is said that revolution by the underclass is inevitable, it implies that systemic inequality and oppression will ultimately lead to a collective uprising from marginalized groups. This perspective suggests that when the grievances of the underclass reach a tipping point, their frustration and demand for justice will drive them to challenge the status quo. Such revolutions are often seen as a response to economic hardship, social injustice, and lack of political representation, indicating a fundamental change in power dynamics is on the horizon.
