Here's some food for thought for you on the budgetary front:

Dépenses = Spending
Recettes = Income

both as a % of GDP.

This is the only time that spending has increased after the recession instead of going down. 9/11 changed everything.
This is also the most massive cut in income that you can see. Coming back on the insane tax cuts for the rich might be a good thing, don't you think? (And the increase in recent months is due to the one-off repatriation of profits by US corporates thanks to the law allowing these to be taxed less than usual)

I'd argue that a good way for Europe to consume more would be for the English language commentators to stop saying that everything is going badly in the eurozone. This has a bad influence on morale, and thus consumption, and happens not to be true:

As to Asia - indeed, they should invest more domestically. But they fear inflation, they fear losing their competitivity if they devalue, and they fear that the US economy will close to them if they stop buying US Treasuries, so it's not so easy.

In the long run, we're all dead. John Maynard Keynes
