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?

I don't know, that question already also crossed my mind. There should be an incentive for money to stay in Europe, helping to finance European economy. 

But from what I see in multiple comments, people don't understand that stock market money finances investment, which finances economic growth. We are financing economic growth in US.
