Unintended consequence

I'm an unintended consequence
The result of all your overconfidence
You're a victim of your own success
I'm the unintended consequence

I'm the cause of all your coming discontent
You can plan but you cannot prevent
Save your family from a shrinking universe
Once the tipping has come there's no return

You've changed yourself to be what you've become
You'll change everything the sun
I'm an unintended consequence when the problem
That you're facing is immense

And the solution that you implement backfires badly
And leads to something worse
To the drawing board once more
And that's your curse

I'm an unintended consequence
The result of all your overconfidence
I'm the unintended consequence
I'm the cause of all your coming discontent

I'm the unintended consequence
And there's no way to calculate the expense
Though you cannot predict when
There's gonna be an unintended consequence
