Some countries (e.g. Greece, Spain) borrowed too much money to pay their public sector workers and other countries (e.g. U.K. and France) lent them money to get a good rate of return and face serious problems as they now stand to lose most of that money if those with high levels of 'Sovereign Debt' default on their obligations to repay.
Petrol and Food have risen enormously recently and put ordinary people under more pressure.
A growing population (and increased longevity) has also put strains on the ability of countries to fund the public sector.
There is now an explosive mixture of countries who try borrowing more money to keep PSW's happy and those who try to enforce Austerity measures, this is because their debt is inter-related as detailed above.
What the answer is we don't know because the economy is now weakening and more people than ever will lose their jobs.
I don't see how spending more to increase wages and pensions can help if it increases the sovereign debt.
Then again I am not an Economist just a worried person who is seeing their savings disappear to nothing and debt looming on the horizon_ _ _
what is the alternative to Capitalism? it's probably so boring and even unthinkable.
