We pay the fear tax every time we spend time or money seeking reassurance. We pay it twice when the act of seeking that reassurance actually makes us more anxious, not less.
Ah, how easily extensible the notion of this tax is. Let's see...how much time every day do I spend seeking reassurance about, say, the political future of this country, on, say the Internet...and feeling more anxious as a result? What are other supposed sources of reassurance that actually--maybe by design--increase our fears?
Should I be worried about this?
