Stop wars, use that money to invest in real life enhancing, life sustaining resources and innovations.
Technology has made it so that we dont have to work that much to sustain our needs, such as food & water resources, shelter, clothing and recreation activities.
In fact if we really wanted to we could automate most jobs to the point where we could abolish the need to make money. We could have a job for everyone who wants one. The places that need workers can hire many people at one time without the hassle the whole money system causes on that process and each person could do 5 hour shifts once or twice a week...
We definitely have enough people for that type of strategy.
There is many ways we can go about things that is much more civilized then it is now.
We can have food (Fruit trees - gardens, ect.) growing all over our towns to the point where there is so much food that no one can monetize it. Or have highly efficient hydroponic tree style architectural grow buildings.
Our Gas & oil usage just proves how primitive we are. As well as our modern world - it shows just how little we value what truly matters... When will people wake up to the fact that you cant eat money.
Having said that I do see many changes in the works right now that are working towards dismantling the powers that be in the light of universal ethics.
On a lighter note I see many great ideas & things emerging from the shit (The same old thing) that the status quo envokes.
Automated robots cleaning our oceans, Off the grid (solar panels, wind, ect) desalination water facilities, Algae power and some real amazing inventions that can turn our money driven world into a world of abundance where to monetize the abundance all around us would be as it is now - insanity.
All we require is an intelligent approach to how we go about things, that build self sustaining cities and towns all across the world. Where the true rights of sentient beings comes into play - universal ethics. We all have a right to live a happy, healthy, prosperous life.
And we have the capabilities to accomplish that, we just need to start implementing it ; taking to heart what matters and following threw.
It would take 10 years from the time we start implementing our current technological know-how/understanding world-wide to have completely re-designed our system to work for us instead of how it works now: against us.
