In the Balance

How do I judge things?
What balance do I use?

Today's rain that waters
Our thirsty desert soil,
Relieves our eyes and souls,
Flooded California yesterday.

The lettuce I eat today
Was someone's labor,
In the hot sun,
His sweat, his sore back.

The clothes I wear
Were sewn in distant factory
A woman worked through the day
Sewing shirts that I wear.

My comfort, my life
Rests balanced on others'
Is it fair, is it just?
How can I judge?
