If economic situations improved for everyone in society, especially the working class, one significant social injustice that would likely diminish is class conflict.
Class conflict arises from disparities in wealth, income, and opportunities, leading to tensions between different socioeconomic groups. When economic conditions improve universally, inequalities are reduced, leading to a more equitable distribution of resources. As the working class gains better access to jobs, fair wages, education, and healthcare, economic stability can foster greater social cohesion and reduce the grievances that often result in class struggles.
While challenges may still exist in other forms, addressing the economic gap can significantly mitigate one of the root causes of social strife and division. This, in turn, could lead to a more harmonious society with fewer conflicts related to social class.
