Expensiveness and unemployment may have been be the reasons for the present hopeless mood  , and governments (across the countries) are  may be responsible for the  hopeless condition of it's people.
In some countriesy condition is  much worse than others. People maybe dead because of hungerry and children left be alone.
One another reason for this hopeless situation  is addiction. many of people are addict Many adults got addicted (to drugs and so on..) and a  new research-probe   says that addictionng is the substance cause to  of  bad moods among adults.
