Hi Marco,

I agree that many of these lists and tables could be harvested (with
some care, of course).

On some are (for example, table for monuments are harvested into Heritage who is now imported on Wikidata).

However, I don't think that the information they contain should go to
the Wikidata item they are associated with. This Wikidata item mostly
exists to store inter-language links, but is poorly connected to the
rest of the knowledge graph. This tax revenue and GDP information should
go to the country items themselves.

In this case, yes, absolutely.
But in some other case, it could be directly into the asociated item (see for instance, this graph : https://fr.wikipedia.org/wiki/Pont-l%27%C3%A9v%C3%AAque#Production ).
 
I am working on the problem of extraction of statements from lists and
tables and will write a tutorial when the tools are ready. WikidataCon
attendees might have a glimpse of that in this session:

Great, I'll be there ;)
