Trees of green

When Louis Armstrong looked around he saw a wonderful world in all of its greatness. I find this though and philosophy stupefying only because I'm not sure I could ever do that. He looked around and saw the blue sky's and green grass. Not war, not starvation, not inequality,but simply the world in all of its purest virgin quality's. People now almost find the jazz tune sarcastic and almost a joke. Were people just more hopeful back then? Or has the world beaten down this new generation into the non-hopefuls? or are we just all numb to the beauty and hideous world?
