Antonio, yours is an impressive and fitting choice to place next to Fahim's picture. Both show men using their own muscles to transport heavy loads, as if they were beasts of burden. This means that they are struggling for just survival to put bread on their table. This means that they likely live from day to day, likely as not, having no other resources. They also have a bleak future as their tends to be no promotion or advancement. Unless the wife has a store or does laundry, for example or he has children at school, there's no hope for better days.
@ Fahim and Antonio: I've taken the liberty of further discussing these two fine pictures here, as a special example of using reference to social qualities and significance as compositional devices.
