Found article [1]: "Now, news outlet DT cites sources which have told the publication that Google was in fact the international web player readying to set bases at the Horndal campus and generate up to 300 permanent jobs."
So $20mm to create 300 jobs? I wouldn't say that ROI is very good in this case. Of course, there were some one-time employment such as contract for building data center and so on, but still I don't see it as a good investment.
Another data center example [2]: "Facebook will build a $750 million data center in the tony northeast Columbus suburb." ... "Peterson expects to employ about 100 workers at the data center."
And for that , government gave Facebook this: "Facebook has a 30-year property tax break on its land, 345 acres on Ohio 161, New Albany Mayor Sloan Spalding said. From the state, Facebook scored a 2-percent, 10-year Job Creation Tax Credit and a 100-percent and a 15-year data center sales tax exemption."
I don't see it as a fair deal for 100 new job positions.

Any company who moved X number of highly skilled individuals to Sweden that's equal to the number of those working in that data center get $20 millions.
Personally I doubt that would work. Such action can only exist as a special deal between the Swedish government and companies which politicians believe brings enough prestige to be worth it.
