There haven't been many serious discussions about privacy or tracking in the US either. The only exceptions might be health data and some financial data, yet much of that information could probably be mined to, using data on purchases and online activity.
Here's [1] just one example of the type of thing that is easily possible. It meant that if you bought a new high end car during the last campaign you were likely to receive a direct mail solicitation for campaign contribution from one or both of the presidential candidates. Maybe that is good or maybe it is bad, but there have been few serious discussions, and during recent years the Supreme Court has declined to recognize most notions of any rights to privacy.
