Surely your question should read: Is life better or worse nowadays - not WORTH.
If life better? Yes, it is. A study of world history will reveal that to you. Just take a look at the statistics of aging. Even as close as a hundred years back most people in so-called Western countries were dead by their late sixties: now its around eighty for men and eighty five for women, so health-wise we're heaps better off. Of course this might not be so thirty or forty years from now with so much obesity in our so-called 'civilized' nations. A lot of people are eating themselves into early graves.
Then we have education. Generally there's little excuse not to be able to be at least literate today. 200 years back only the very rich or people who were church officials could read and write.
Nowadays there are far more opportunities for people to make a good life for themselves than in any other time in human history. All manner of people can rise to their fuller potential. Not so back in the days of old when a few ruled over the many: lords and serfs, rulers and slaves.
Is life better or worse nowadays? It is much, much better...and keeps on getting so as time goes by.
