Pumpkin Spice Lazarus - Not sure I'd agree with how you characterize it... but if you're genuinely asking the question and not trying to make a statement: there's a body of intellectual thought that informs liberal ideology, just as their is a body of intellectual thought that informs your own ideology.
On the left -- they are more likely to take into account things like adverse childhood experiences lowering the probability that someone will be successful, capable of overcoming psychological problems, coping with stress, and so on in order to perform as well at a job as some others.
& they might take into account cycles of poverty due to lack of education. Even something like simple childhood literacy -- parents reading to young children on a daily basis is proven to dramatically increase the likelihood that the child will perform will on standardized tests in the 3rd grade > which is the strongest indication that they'll perform well throughout the rest of their education, and naturally excel in the real world post-education.
So -- in short... the liberal mind is more inclined to evaluate multiple variables. Whereas the conservative mind is more inclined to see everything as a result of effort and free-will.
The problem is, the left uses childhood problems, broken homes, poor education, etc.. as a kind of excuse.
Then they turn it around and attempt to put the blame everywhere else, such as rich people, racists who lived in previous centuries, etc.
If a person is indeed born into an underprivileged situation -- wouldn't the "conservative" outlook you speak of, tend to be more beneficial for that person?
It seeks to me that a more liberal outlook, tends to enable people who are struggling, by encouraging them to blame the world.
A person who is blameless might be more justified in accepting the status quo -- and even taking it further to justify poor decisions or criminal behavior.
Obviously this is a rabbit hole of a subject, where variables, exceptions, and outliers are endless.
Maybe it's better to see both sides of it, instead of clinging to an "ideology".
