eBay bringing down profits and bastardizing the marketplace

I started buying and selling on eBay since the beginning. But over the last 10-12 years the marketplace has become saturated. Antique and collectible stores now have to try to compete with this juggernaut. This means that in most cases, slashing your prices by 50% to 60%. What does this mean to the average collector? Your prized comic book collection is now worth only a few hundred dollars instead of a few thousand. This is great for the average collector that wants a few pieces at a bargain price. But if you have been collecting for decades and planned on using your collection to either put you through college or help buy your first home, you are out of luck.  In the end eBay can be a great outlet to quickly get rid of a few things you have no need for. But it has been destroying the antique market many many years by bringing down profits of the seller’s that have searched for that prized action figure you have been looking for.
