Yes, I am grateful - I feel lucky. Yes I believe everyone in the world can afford to live a fulfilling life with plenty of everything. The primary reason people suffer from lack is because they are idle. We merely need to fix the system a bit. You can grow healthy food almost anywhere, we have terrific technologies for this. You don't need to use petroleum-based fertilizers. The now improved
French intensive method works even better than that and it improves the soil rather than depleting it. This is just one example. I think if we repaired what is now a broken system we could come up with better methods for nearly everything we do. It's how human beings evolve.
This may sound foolish to some folks, but from my point of view this disbelief comes from the fact that they believe the big lie that there is not enough. Obviously there's more than enough, look at how much of our resources we just throw away - we make disposable goods from finite resources. This has to be addressed as part of the shift, but once it has been things should improve - we are trying to address it with recycling.
With functional and sustainable methodologies for creating the necessities of life all of the world could enjoy plenty and create their own wonderful things that they can then share with us, so everyone's life improves.
