Does the original Willy Wonka film have social commentary elements?

Brilliant movie! I think I'll watch it today, as i am recovering from
a injury and have nothing else to do.
Do you think that this movie has social commentary elements?

Or do you think it just reflects normal people in outrageous
circumstances and takes on fantasy elements by also exaggerating these
normal people? Know what I'm trying to say? I'm not saying I'm right
in the way I worded it, but I am trying to say something.

PEACE...and please, be nice, kind. Respond please if you understand
what I think I'm trying to ask here.
