While the lack of any acknowledgement of BoB Day is a travesty, I think what you've described is the net result of the time that has passed since WW2. In today's hustle-bustle world, WW2 is ancient history.
While the BoB was a defining moment (IMO, anyway), it's rapidly receding into history much as other (then) major events have done.
Using the US as example, look at Dec 7 -- Pearl Harbor attack. Another defining moment which received a few seconds commentary at the very end of the evening news last year. Same for VE/VJ day over the past few years. The one notable exception was 2005 -- simply due to it being the 60th anniversary of the end of the war. Next year it will once again be a passing footnote, if mentioned at all.
Depending on your age, the view of WW2 can skew markedly (being in the US, I'm using US history as my example). To someone born in the 1950s/60s, WW2 was the dominating event -- being barely 10-15 years in the past. This war was fought by fathers, uncles, and some grandparents. WW1 was the war of the grandparents -- about 40 years in the past. The Korean War was less than 10 years distant and the looming disaster of Vietnam was just beginning. The US Civil War ended 100 years.
Fast forward to those born in the 1970s/80s. WW2 was fought by this generations grandparents. The war ended 30-40 years previous. Korea was a stalemate eclipsed by the legacy of the "last good war (WW2)" and the debacle of the freshly-ended Vietnam War.
Forward to today. To the youth of today, WW2 looks the same as the Spanish-American War (1898) did to a child in the 1960s. Using the same comparative views, the Korean War appears as WW1. The Vietnam War approximates WW2 and the first Gulf War occupies the place of the Korean War.
Most of us will (hopefully) make it to the 100 year anniversery of WW2. Using the above comparison, the view of the youth of this timeframe will be the same as the view back at the US Civil War or the Franco-Prussian War.
On the positive side, reenacting/living history is thriving. As result, the sacrifices of the WW2 generation will continue to be honored and remembered.
