Lowering the public debt burden is not an end-in-itself. Debts could serve to stimulate the economy and improve the living conditions of the victims of the crisis. Debt reduction must occur by increasing the (tax) revenues (through higher tax rates and combating tax evasion), not only by reducing spending. Stopping the austerity measures has absolute priority.
Inspiring people must not be an easy thing to do. It seems you can't just get them to buy into a lot of promises, especially if they take a first step, without them expecting you to make good on what you said. Maybe when a person makes certain promises, with the caveat those people the promises were made to take the initial step, the people that made the promises are even more likely to be held to high standards regarding fulfilling them. In fact, adults rarely take first steps where they are truly putting a lot in another's hands, unless they have trust in that person.
