Great question. I'm a bit surprised that this forum is as little used as it is - I've been aware of the site for several years and have been in and out of re-enactment since the mid 1990s. (Our re-enactment unit even self-published a history of our group in hardcover - available here

AffordabilityI have to agree that 2008 would have seemed to be the time to get involved (2009 is more understandable, with the economic downturn) - uniforms are dirt cheap - I know, I was selling panzer wraps on ebay. They were my favourite of the German uniforms and so I found a supplier to do up replicas out of Pakistan. Made good money until rip off artists in Hong Kong started undercutting me with inferior material, but superior cut - guess what shows up in an ebay listing? Even offering a complete range of choice of insignia didn't help, and I was only doing it as a hobby a half dozen at a time - they were selling in bulk out of Hong Kong. I switched to assault gun wrappers in field grey, but soon they were making those too, and so I took my money and found another hobby.
But the point is, all that competitive drive overseas means you can get not just uniforms but field equipment dirt cheap. Any Pakistan company that does business with you reports to the chamber of commerce there, and you're suddenly on the mailing list for all his competitors, and EVERYONE seems to be making MP40 pouches out of canvas, mountain troop caps, peaked caps, BEVO sleeve eagles, leather belts with Wehrmacht buckles, probably more stuff now coming out of south Asia than the Germans produced during the war. And of acceptable quality - anyone paying too much from third parties in the States or the U.K. should contact the suppliers directly in Pakistan - for the cost of sending a sample, they'll make anything you want.
But I digress
Public BattlesPublic battles for World War II are largely, from what I've seen, a joke. I've participated in a couple, and while the guys who do them are well-meaning, and the ones I've been in have been well-received and went off more or less successfully, they don't do what the Civil War public displays do. You could never convince anyone to drive across town or a state to attend one, like you could a Gettysburg re-enactment, because it will never be an "event" unless you happened to be at Arnhem or the Normandy Beaches. You can't recreate a World War II battlefield very convincingly either because most battles were decided by artillery and the combatants made a practice of not being able to be seen. The battles took up a lot of space and were fought over hours and days. They didn't lend themselves to mass spectacle.
Public displays of living history encampments are far more successful, but apparently less popular among the guys who own the jeeps, tanks, and machine guns. Not a surprise.
New generationThere probably is something to the point that World War II is becoming a distant memory, as far as collective public consciousness goes, but if the American Civil War can retain its significance I have to believe the Second World War will also. The problem will be in convincing a 20 year old college student that he wants to spend 500 dollars on buying a gun and a uniform and cutting his hair short and staying physically fit, particularly in post-war, post-recession America.
Rugged IndividualistsThe biggest problem we faced in our unit, and bear in mind there were only three of us at the very core of the unit, was that we each had our own ideas of how we wanted to do things. I've seen stories of this in every organization I have come in contact with, or read about (if you haven't read Jenny Thompson's book WARGAMES yet, you should do so -
http://www.amazon.com/War-Games-Inside-Twentieth-Century-Reenactors/dp/1588341283 ). There is a basic lack of willingness to compromise among re-enactors, and I'm not sure where it comes from. Perhaps it is lack of leadership, perhaps it is the fact that as a quasi-military organization,
everyone wants to be a leader. But everyone wants to do things their own way. I'm as guilty as anyone. And there is a very real feeling that goes something like "hey, I paid 1,000 dollars for all this 'stuff' and if you don't like the way I'm doing things, I'm going to take it all and go home."
The attitude is both pervasive and permissive. For example, a 500 pound Fallschirmj?ger can parade around because he's the guy who owns the automatic weapons.
"Hey, isn't that guy kind of fat - how would he even fit in the door of a Junkers?"
"Oh, he owns the machine guns, so we let him dress up - don't worry, he won't be coming to the field with us."
"Oh, so he's just staying here in the public display area where the public can see him."
"Yeah, so no harm done."
Why object, right? Because everyone is in charge, rules get bent, changed, modified, and people get fed up with it all the time. Hop from one organization to another, make their own unit when they get tired of another, start a new federation, quit, sell their stuff, rejoin two years later.
At the end of the day, though, the fact that it is still just a hobby is probably it's saving grace. There is money changing hands, but only in relatively small amounts, for kit and registration and event fees. Were reenactment to "turn pro" that's when your real headaches would start. And for heaven's sake, don't let the government start running things...
