The Tesla Berlin car factory alone costs 4 billion euros. A large part of this sum is going to local construction companies. So in some sense, they already paid for it.
If the government gives me €1B and I go buy gold with it, just because I’ve spent it locally does not make it a productive use of proceeds.
Buying up stores of wealth instead of purchasing services is a very bad way to stimulate the economy.
It takes a hell of a lot to justify these sorts of investments and usually the ROI doesn’t materialize for the State.
That doesn’t mean you can just argue a point without any sort of justification.
>The history of these things is overwhelmingly that in the final tally, actual benefits fall far short of break even.
Do you have some source for this?
