There's a difference between being responsible (having the obligation to take action) and being at fault (being the one who actually made the bad decisions that led to the situation you're in).
Most of the decisions that led to this situation were not made by me.
And the few cases where I'm genuinely implicated are 'trolley problems' set up by people who are more directly responsible, because they are more powerful.
The most effective response is probably political action.
