There has emerged a degree of pessimism here centered around the Global Economic situation.
In 1949 . . . Albert Einstein said . . . "A largely unregulated capatalist system will eventually result in the greatest tragedy for mankind"
We appear to be approaching that point. I don't see this necessarily as bad as it might seem. Even a "collapse" of the current economic system will not be as sudden as some might imagine IMO. Countries with weaker economies will undergo change first (as we are beginning to see) and usher in changes that will see Global Economics change for sure.
The increase in competition for resources will drive some populations to a more "subsistence" style economy with simpler life-styles and a more internalised "local" distribution of resources as international markets become more unstable.
For the individual . . . land ownership and working towards a higher degree of self-sufficiency would be a wise course to persue IMO. The greatest threat could come from lawlessness resulting from the austerity imposed by simpler life-styles. Humans collectively will find the changes painful in one way or another . . . but the human race will survive this change . . . and eventually be better for it . . . hows that for positive? . . . no?
See . . . nothing to worry about really.
