The Left

A lot of derogatory terms are bandied about by proponents of market led policies to describe left wing policies.

Left wing politics is described thus in Wikipedia: Left-wing politics supports social equality and egalitarianism, often in opposition of social hierarchy. Left-wing politics typically involve a concern for those in society whom its adherents perceive as disadvantaged relative to others, as well as a belief that there are unjustified inequalities that need to be reduced or abolished. According to emeritus professor of economics, Barry Clark, left-wing supporters "claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated." 

Could anyone on the market led side of the political divide tell me what's wrong with that? After all, it was the system that brought about civilization itself. 

Left wing policies would have avoided many of the deaths in the Irish potato famine, whereas market led policies directly resulted in a million dying. 

Left wing policies are being used the world over today to combat Covid's effects on economies, whereas the worst affected countries tend to use market led policies.

Market led policies ignore the consequences for and on people; they're impersonal and mechanistic. Left wing policies, on the other hand, put people at their core.
