Maybe you could point to one country that has managed to spend its way out of a financial mess.
When governments spend money it has to be taken from somewhere because governments do not have money of their own. Either they find their spending through immediate taxation, or through deferred taxation, i.e. borrowing. Either way there is no net benefit from government spending as any mi ey put into the economy is also taken out.
Ireland is currently financing spending is the worse of the two options, i.e. through borrowing. The negative impact of deficit spending is two fold, (a) there is less credit available for the productive sector and (b) the money has to be paid back plus interest thus increasing the need for higher future taxation.
Economic crises have never been solved through increased spending, this has only ever led to prolonging of the crisis.
