Great questions raised.
I would immediately like to address the very nature of the poem, which is expectation, upon the very first reading. The very idea of expecting a reward of any sort for one's actions is toxic on many levels at its very core. To elaborate, I wish to use your poem to detail what I mean by this statement.
Firstly, it is natural for people 'who can't use their heads' to impulsively react to actions of others in laughter. The reason for this is misunderstanding - a simple lack of common ground upon which an understanding can be built between the two. The one laughing is simply incapable of seeing the actions of the performer from the point of view of the one performing it, so why then should the performer be concerned with the laughter? It is futile to respond to such behaviour or to even take it to heart. It has nothing to do with the performer. The laughter is a habitual act of the person asleep and unaware of the diversity of life. There is one existence, yet there are infinite ways of interpreting that very same existence. Do not feel ashamed by your interpretation.
Your usage of the word 'injustice' strikes me. You say that one working like a slave and reaping the harvest of one is subjected to injustice, yet what else is to come as a result of working as a slave? To put things into perspective, it is similar to suggesting that an artist sketching in pencil and ending up with a tonal shaded portrait as a result of his actions is subjected to injustice as his work of art lacks color. It is not what one does that holds importance but how one does it. Any action performed with mindfulness and complete awareness is a seed of greatness sown in the garden of love.
On what basis can we strive(?)' you ask. My response to this would be: do we truly need a basis upon only which we can strive, or is it possible to simply strive? Dependancy on a guarantee of some sort of fruitfulness diminishes the beauty with which we sprout and grow.
