Most poeple think that they can rob peter to pay paul. This only hleps to get our problems delayed and does not eliminate them. If we delay too long in repaying the debt then we get to the position that the economy has gotten to.
The main reason for "debt consolidation" is to put all debt in one basket which will allow you to lengthen the time that the debt can be paid back which lowers the monthly payments and gives you some liquidity, but this usually also increases the total amount that will be paid back over time so most debt consolidation actually increases debt.
There are times when the above statements are not true and the debt consolidation actually lowers the overall debt. When this is the case it is a very good thing!
