Something has changed or it’s just my fantasy?

There’s a real force here. The dumpster image is ugly in the right way. It makes the whole poem feel dirty, man-made, and avoidable, which fits the subject perfectly.

I also like how you keep bringing the reader back from power and strategy to ordinary human cost. The child with the notebook, the balconies, the smoke, those details keep the poem from turning into a speech.

And the ending is strong because it is so simple. The fire was never the problem by itself. The hands were. That lands clearly and stays in the head.
