On the other hand, even fewer have their recommended yearly checkup:
"For working-age adults ages 19-64, 38.7% had a dental visit [in the past 12 months]." [0]
As you say though, the shot may not be everyone's preference, but it will be great for many.
The "already taxed by the estate tax" justification is ridiculous to start with. If you have unpaid income tax it doesn't get waived to avoid "double taxation"; certainly you don't get a refund on all the taxes already paid on your savings. But if you kick the can down the road long enough with unrealized gains then you get a special bonus?
