Thankfully polling has been done on privacy issues with results freely available to all: http://www.pewinternet.org/201...
Here's the problem with the poll - they ask people about privacy, security and surveillance - but they don't test to see if people understand those topics, or how much they REALLY care about it.
For example, people claim they care about things being made in America - http://washington.cbslocal.com/2013/05/01/gallup-60-percent-of-u-s-willing-to-pay-more-for-american-made-products/ - However, one look at how much we import from overseas, and it is obvious how much they (don't) care.
Here's a (bad) car analogy - if I asked, "Do you want cars to be safer?" Most people would probably answer, "Yes." However, if I followed that with, "Do you want cars to be limited to 35 MPH?" Most people would think I'm crazy.
Here's the reality - even people who are aware of their data, how it might be shared, and are actively trying to protect it, are leaking data like a sieve. Most aren't willing to go to the lengths necessary to protect their information properly. Using gmail or any web mail provider? You are leaking information. Buying something online? Name, address, credit card info. Carrying a cell phone? GPS location and contacts. Using iCloud, Dropbox or any online storage service? I hope you have everything encrypted - and I mean your encryption, not their baked in service. I also hope you have never accidentally clicked a link or ad you didn't intend to (or even intended to) - because that info is going all over the place.

You might claim you care about privacy, security and surveillance; but how much effort are you really putting into protecting it?
