Who were suffering due to laissez-faire policy and championed the ideals above?

Those suffering due to laissez-faire policies were often the working class and the poor, who faced exploitation, poor working conditions, and inadequate wages without government intervention. Labor unions and social reformers championed ideals of social justice, workers' rights, and increased regulation to protect vulnerable populations. They argued for the need for government action to address inequalities and improve living standards. Figures such as Karl Marx and social activists in the late 19th and early 20th centuries advocated for these changes in response to the adverse effects of unregulated capitalism.
