The problem is pretty simple .." The system " encouragres debt ..so the whole wealth creation issue ..its run on debt .This is the problem for property spukiers ..Im sure it works for them , but its impossible for the system to work if all thing they can " have a go " .The real problem of middle class debt is if the people start buying into the wrong asset classes , taking holidays , buying cars ..some renovations and entensions . You just cant " teach " ..a system , yet the taxation benefits support your decision .Debt free with a large income .... does not provide the ultimate best position on the assumption the asset class will grow .
The middle class ..have " felt " rich ..and generally used their money ( or credit) in the wrong sectors.
