I would assume the government would require services and large teams to help them make sense of the data along with the low the infrastructure described by the article.
I am pretty sure they can't make sense of the data, nor can they afford the sort of talent that might be able to make sense of the data. So they do whats easy...just keep collecting more.
It's much more efficient as an employment/pension guarantee scheme than an efficient intelligence tool.
Reminds me of the qoute from Yes Minister - Something must be done. This is something. Therefore we must do it.
