Sure, other people who lived a much harder life would think that our current times are fantastic. But of course our own perception is what counts when it comes to our own pursuit of happyness.
And of course, even today there are still millions of people who’s life isn’t that far removed from peasansts in the middle ages. Not to mention the still waste amount of difference in life quality and prosperity between different regions on this planet. Just because I’m happy enough to be born in one of the best places on this planet doesn’t mean I can’t realise, that many people have it much worse and that there is so much room for improvement if we overcome the greed of a few powerfull people.
