Libtards have certain irrational beliefs:
1) malevolent sense of life: anti-man, anti-life
2) malevolent universe mentality: the universe is inimicable to man and man by his very nature is helpless and doomed
3) pathological hatred and fear of economic progress
Only a modern collectivist would see this as "unfair", and demand that something (i.e.- State action) be done about it, in the form of forcible redistribution. Traditional Western civilization depended upon common values and frequently self-enforced good behavior of its citizens in order to thrive in a marketplace largely free of government intervention, though certainly not of objectively-applied laws.
Leftists have turned this world upside down, breaking the voluntary bonds between individuals (largely: families and churches), making laws subjective and unknowable, vastly increasing regulations and taxes, and replacing the idea of the cheerful self-reliant citizen with that of the Despondent Dependent.
Why? Because in their hearts, they are destructively anti-human and anti-Good. Because they are driven by fear and hatred to deny responsibility for their own lives (and objective reality) because the success and achievement of others serves as an affront to them, rather than a model to be emulated.
