The world is rich in raw materials, technology, knowledge and human "doing power", to the extent that if the world was organised in a different way everyone would enjoy a comfortable poverty-free life.
Why don't we re-organise society to reap the benefits of these scientific advances? Because governments (which people put there) all look for solutions within the framework of the money/wages/buying-and-selling system of society.
History shows us that capitalism was set up by a minority of people (the owners of capital) to run in the interests of that minority. If we all had enough capital, we'd not be compelled to become wage slaves – then who would do the work?
So, if there's no profit in it, there's no production of it and no supply of it. That's the way the system of today works! If you can't afford it, you'll have to do without it.
Some people (because they've been encouraged to think solely in terms of money, wages, buying and selling) will undoubtedly dismiss any alternative as a far-off dream. Others will claim that human nature will make it impossible.
It's essential that you understand and believe in the ability of people to change, or you give up any possibility of serious change in society.
The alternative is the world belonging to all its people, producing the things we need to live and enjoy life. Directly meeting people's needs! This means no money, wages, buying and selling.
Why should we have to buy back what we've collectively produced?
This outmoded rationing system must go. There's a world of abundance to work for. Work would be co-operatively organised on a voluntary basis. Everyone would have open access to what they need, and an equal voice and vote in decisions which would affect their lives.
