Yes, it's a profound thing to threaten someone's livelihood, though at the same time, society will squash individuals when genuinely threatened; never doubt that for a minute. For a time, it seemed like the vaccines might stop transmission of covid, but that seems to have been a bust. They do, however seem to rather clearly help an individual's response to the virus, and so it seems like it became a matter of individual responsibility.
As to the fish thing, you understood me correctly - when we are born, we are thrown into a world we did not create and have vanishingly little control over, and seemingly less as wealth and power accumulate into the hands of a few. I'm told that well-adjusted people are capable of adapting to their circumstances, and it is a mark of mental illness that one can not.
