History as an arrow

Did the renaissance do anything?
Not if you really look at the politics
it did not get rid of the feudal system,
it was for the wealthy - the little people
were ignorant - kept dumb and down.
The church in Europe was still strong
yes, there were mumblings about
some other political system
way back when Greece was young
and Socrates were running around
but truly it did not get rid of
superstition, superimposing beliefs
but there was one area where
the renaissance blew everything away -
art and architecture.
Did the baroque do anything?
Galileo with his The earth moves anyway
Decartes saying, I think therefore I am
and Hobbes changed the political system
cause people are not nice, needing
a firm hand -in art, architecture
and music - it also excelled
with voluptuous odalisques and
funneled, crenelated pilasters.
Did the Romantic period change anything?
All the technological discoveries
that finally bloomed with blood
sweatshops and tears, but in the music
it excelled with Mozart and Beethoven.
So can we conclude that even though
on the surface - the waves seem small
they just keep coming - growing
and history wipes the world slate
clean of blood - mistakes - plunder
and humanity can change - mayhap.
