Should Greece people worries about their own economy

conversely, as the chart shown that Greece economy witnessed dramatically drop since late of Oct, 2007, the chart also shown that huge drop is near to finish and the dark cloud almost is disappearing, so I find myself that must assure Greece people that your economy is getting better in next few (days.. months .. years), Additionally, I would like to recommending them to buy as much as they can good performance stocks ;)
