A slam poem is basically a poem that disses something. Is it obvious what I'm disisng? If not how do I fix it?

The only thing that come out of your mouth

Is complaints

A roof over your head

Food on the table

Clothes on your body

Not grateful for a single thing you have…

You still complain

I don’t think you realize that there are...

Thousands of people without that

Struggling to survive

Begging on the streets

You say you’re better off dead

But thousands would kill for a life like yours

They say that pleasure

Is absence of pain,

But to know the sun

You must know the rain

And you my friend,

Have felt neither
