In these precarious socioeconomic times, I would say money and lots of it. This perilous socioeconomic climate with its high unemployment rate and job instability with people two to three paychecks away from homelessness dictates the necessity of having monies especially investments and savings to keep one afloat.
The only people who are somewhat secure and seemingly unaffected by this economic climate are those with quite substantial incomes. They do not have to worry yet. The majority of the population must worry. If their jobs go under and if they do not have sufficient funds, they will be the next to be homeless.
Money, of course, is more important than relationships. This is because monies are the difference between struggling for a living and thriving and living the successful life of your dreams. Monies is the difference between having a home and living on the street, being at the mercy of welfare systems which often exploit the indigent. Monies is the difference between living in a good, safe neighborhood and living in one where your existence is often perilous and frought with mere survival against its denizens.
