There is a political element to some of these ceremonies and they do focus a lot on WW1 and WW2 and I do agree its all getting a bit much. I do think the 100 year WW1 anniversaries have contributed to this.
To answer the question the events don't help solders today, I would say the money raised from poppies goes to help people alive in the armed forces and particulary ex-forces who need some form of support.
In my family WW1 indirectly contributed to orphaning my father at 15 and I believe this had a negative effect on his personality and life. He died in 2005 and so I can see the long psychological shadow that that war cast long after 1918, in our family. Quite a lot of what happened to frontline troops was brushed under the carpet and it stayed under the carpet, with sometimes disastrous pyschological effects.
Recently I went to the newly opened Holocaust Galleries at the Imperial War Museum. This is WW2 period and has a political element, but I personally still think its important to learn and remember and try and avoid the mistakes of the past, in the future. The Galleries have been designed to take the visitor on a journey of how the Holocaust gradually happened over time, often quite slowly.
