It may be said that generally the standard of living today is better than the standard of living in the past (however back we may want to go) especially in terms of material advancement, except for the poor for whom the earth does not seem to belong to them.
What I mean is that, if we are to reflect, what we are enjoying or could enjoy today is much better than what our parents or grandparents did enjoy or could have enjoyed in their times - in general of course. If we think that the smartphone is anywhere superior to the land-line or the post, then the statement is true. If we think of the benefits of clusters in towns compared with solitary isolation in remote villages, then the statement is true.
There will be those who argue that the world has gone wrong and going back to the simple life of days gone by is the best thing to do for mankind, and they will disagree with the statement. There will be families who used to have great fortunes and are now reduced to poverty, then they may be also disagree. But in general, I think it is fair to say that life today is much much better than before.
The point is that, regardless or where you are today, be it Washington or a far flung island on the South Seas, regardless of the size of your wallet or the number of vacant real estate that you have managed to amass around the world, as you sit quietly in your own home, you must surely feel that you are lucky to be alive today and have the opportunity to enjoy what the world today has to offer. I have often said that life is like a buffet lunch - you can choose what you want to consume.
The prosperity of the world today is the variety of goods and services that are in the market for anyone of us to consume or try to consume (like that Leica Monochrom whom most of us cannot really afford). We may not in the end consume them, but to have that opportunity is a god-send.
As the markets grow and the world shrinks, it is really up to each of us to what we want to do in order to enjoy ourselves while we are alive in this world. There could be other worlds, but we do not know for sure - though we can imagine for sure. The certainty is now, and now is real.
