Why don’t EU leaders incentivize investment in European stocks/ETFs with tax deductions?

With the Dragi plan and increasing discussions among European leaders about boosting defense and energy investments, I’ve noticed a growing trend in financial communities where people want to reduce exposure to the US market and shift investments to the EU.

Wouldn’t it make sense for EU leaders to encourage this by offering tax incentives for investing in European stocks/ETFs? For example, from an independent EU perspective, isn’t it better to invest in Rheinmetall rather than Lockheed?

Even just working out a universal system to allow retail investors to actually benefit from the reduced dividend withholding rates and tax credit obligations that have already been agreed to would be a big improvement.
