It's simple:

Think about it, a CEO of a big company is more likely to be in social circle of the politicians, judges and regulators.

They are more likely to be sympathetic to their immediate acquaintance who they see every week rather than those poor social economic class people who they have nothing in common with.

Add some dilllusion and descrimination in the mix, like "they are poor because they are lazy" and it becomes easy to make policies which benefit your immediate social circle.

And lot of poor people don't even have time or motivation to analyze those policies and even if someone manages to do that, they don't have enough influence to do anything about it.

Even simpler. The folks in a company that can write checks, write them to each other.
