Replaceability

Peril? Let me tell you what's perilous:
The idea of replaceability;
At surface there's nothing to tell amiss,
But in its irrefutability
It necessitates culpability. 
In our societal lust for progress,
The strong force the responsibility
Down the line onto the many cogs less
Powerful or advanced than these august
Lords of capital. Then when they're displeased
They dispose of people as a process.
That's how they attained the power they've seized.
And sadly it's true, inevitably 
Someone comes to fill the voids that we leave.
