Hi Marco,
I agree that many of these lists and tables could be harvested (with some care, of course).
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.
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: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2017/Submissions/OpenRefi...
Cheers, Antonin

I have noticed a lack of actual data in wikidata representations of wikipedia list.
for example
List of countries by tax revenue to GDP ratio https://en.wikipedia.org/wiki/List_of_countries_by_tax_revenue_to_GDP_ratio
to
List of countries by tax revenue as percentage of GDP (Q2529105) https://www.wikidata.org/wiki/Q2529105
is there currently a development in the wikidata community to transform these lists into wikibase items and last but not least produce RDF respresentations for WDQS?
best, Marco
