Things are changing, and the industry of racing is going the way of Polo, which use to be enjoyed only by the super rich as an affordable extravagance activity.
The United States use to be king of all such extravagant activities. With money to spare, and ticket sales beyond to relm of a fortune, everyone having bountiful employment, things were very good for the majority of americans.
And then the powers that be decided it was time for that money to route to a different source, a source that could lead right to their bank accounts, because americans had been foolish with their money, and it was time they were relieved of that money.
So changes were put into production to get americans back on track, the track that leads to government control of their finances. Gas was slowly allowed to go up, up ,up, and the rains on business lending, and spending was kept very loose for a while, interest rates were lowered, banks were encouraged to become laxed in their decision making, and credit card rates were allowed to rise while brokage firms were telling lies to get people to invest, insider trading was at an all time high.

Then it happened, everything collapsed, and all at the same time, a well planned out conclusion to start something that would lead to the people begging the government to please help, help with something the government created.
So things changed, and will continue to change, and things will continue to fade out that we really don't need to spend money on, because now we need to focus on just surviving.
