Euro zone: What form would a revolt of the savers take?

The fact that interest rates are considerably lower than the growth rate in the euro zone is a significant tax on savers, which they currently accept. But could they revolt against this tax in the future? This revolt would take the form of: A refusal to hold bonds with very low yields, which would force the ECB to resume quantitative easing and to buy the bonds sold by investors and savers; A portfolio switch into risky euro-zone assets (equities, real estate, high yield), whose prices would then rise sharply despite the rise in long-term interest rates, or into bonds from regions offering higher yields ( United States , emerging countries), leading to a steep depreciation of the euro.
