I think the poem is expressing that we have more power than we think we have. But we keep doing things that are not important like spending money on things that will be wasted later.
Explanation:
I say this because the line "we waste our powers" has so much to unpack here. Wasting your powers could mean giving it to someone else like a toxic, racist, boss. Wasting your powers could mean you see things happening and you choose not to do anything. Wasting your powers could mean literally anything. And I think that line is the key to the poem that touches a lot of hearts.
