Batting averages for tailenders this decade are certainly down, but for Australia, at least, they are higher than the 60s, 70s and 80s, and a touch lower than the 90s.
For what it's worth, the global batting average of tailenders since the IPL started in April 2008 is 15.79, compared to the all-time average of 15.25.
I’d be guessing averages for batsmen in general are down this decade
