Hidden message? (some small spoilers inside)

Just finished watching this anime! Loved it! 9/10!
It's very inspiring and has a good leadership message and motivation (very Sun Tzu like).

Maybe this show is a satire to our society and class diferences, in which meritocracy and entrepreneurship is a heroic effort.
I was just wondering if the Titans could be the very rich who devour mankind sucking our lives. Nothing against rich people...only the ones who get rich by being parasites of others (corrupt politicians and other people who get rich by exploitation,etc)

The possibility of humans turning to Titans in this series also adds to this theory...

Also the different walls separating the bourgeoise and the poor people.
And the religious side thinking the Wall is of divine origin and hoping praying helps them.

The show is full of messages pointing this way.

Anyone thought the same?
