What went wrong?

WHAT WENT WRONG?
Teacher, Teacher, Teacher
I train the future leader
To climb the ladder
I set the pace
For the race
The dumb, I train
Whether shine or rain
When parents are busy finding fortune
With their money-making machine
When their stubborn wards are sacrosanct
In their elemental pandemonium
I am there to nurture them

Doing all this, I can say
Is to help them find the way
Sometimes, though tired
No other way than to get their brains wired
I laugh in class, though I’m wounded within
To get them inspired
I sometimes have to forgo pleasure
Yes, even my leisure
I sit behind the books
Searching for information
That will take them to their destination

Yet, after my sacrifice
Not even a bowl of rice
The same parents despise
Me, in front of their wards
Why would they bite
The hand that feed them?

Not their fault, I think
Even the Gentleman mocks me
After training him to see
His desired position
He laughs with disrespect
And echoes his unguided comment
To the world, to portray
His unwillingness
No, his meanness
To me, his trainer

And to my own people
Who call themselves
The voice of the voiceless
The leader of the led
You sit aloof and watch
With unconcerned pretense
While the trainee mocks your own
Are you not part of my woe?

I have been thinking so hard
About this disregard
Explain to me this song
“What went wrong?”
