I'm not sure from what you said whether you understood my point.

The example quotes are not biased at all if they used language to convey a deeper and accurate sense of reality.

The bias comes not from using implication to deliver information. It comes either from

(1) using implication to give a worse and less accurate sense of reality (but one that better comports with the writer's opinions), or

(2) curating which bits of reality to present so that the recipient ends up with an inaccurate view of the frequency of occurrence of things in reality

Because in your examples you do not give us ground truth reality, we cannot judge whether (1) is the case. And because you give only one example, there is no frequency information so (2) cannot be the case.

Therefore, the example statements definitely had implicit content, but we cannot judge them as anti-affluent or racist or anything. We need more context. It might not take very much context, but it takes more than you gave.
