Itvis a very simple principle. Managable debt is not a bad thing, you do not need to have the capital to be able to afford something, you simply need the ability to repay over the chosen periods. 
Personally I have no net debt and that is the key, when your assets are outstripped by your debts then you need to evaluate your position financially. The problem with some individuals personal debt, is not the fact that it is debt, but that it is poorly managed and their debt is significantly higher than their assets or ability to pay.
Sometimes it is financially prudent to use credit facilities, sometimes it is not. How you manage those decisions is the issue.
