It has already started. You just misunderstood it. He was saying that your wallet will be saving on the burden of having to carry around that $2,500 you would have otherwise had.
Interestingly enough, I will end up saving about $500 this year because of it. Since I have a preexisting condition I had never really been able to buy decent insurance and always paid for my expensive medication out of pocket. Now I have much better coverage at a little higher rate than I was paying, but it has better drug coverage. However, I do have a deductible so when you add it all together it will net me about a $500 savings compared to a typical, average year.
Of course if I have a lot of doctors appointments or something were to happen where I ended up in the hospital my savings would likely be much more.
