The EU doesn't invest, the EU provides subsidies with many strings attached. One of the strings usually is "can't be used to pay shareholders" (as in wages, not just dividends). Also, the subsidies are usually provided after the fact (e.g. a project is completed) and you need a loan to actually do the project. That's a risk, and banks don't like providing loans to small companies without predictable cashflow; they would do it only if a shareholder with enough assets personally underwrites it - another huge risk, now a startup can destroy your whole life.

If you meant the investors of EU - please show me where you got the data, because the official EU data suggest otherwise. People simply aren't that rich around here, which is a downstream effect of the much slower, smaller economy.
