Fact: you can't be world-class-fast if you're a heelstriker.
You need to land forefoot or, if need be, midfoot. HELLstrikers automatically add a braking effect to every stride.

Quite the opposite actually. Heel landing loads the whole leg better for elastic recoil.
Watch a slo mo of any race from 800 up, even including the 800 and you'll see mostly heel striking or mid-foot at best.
Dozens of pics taken at the right moment show this.
Even sprinters touch down ahead of their center of gravity.

Somehow I think that foot strike falls outside of the top 10 reasons why "you" can't be "world-class-fast".
You're only braking if you land on your heel while your leg is moving forward. If your leg has started moving backward you aren't going to have a braking effect.
So what youre saying is that men has only begun running fast since Nike invented the cushioned running shoe.
Barefoot or wearing uncushioned shoes you sure aint going to land on your heels.
Ergo: running fast over more than 200 meters is a very unnatural thing to do for humans since it can't be done without wearing aerobeds under your soles.
The thing you got right is that all those high jumpers sure missed their calling. Those guys are vertical oscillating like mad, you know!

That's why you need to wear shoes with as minimal a drop as possible. With a zero drop you can preload all the way and still land on the balls of your feet.
You can preload all you want. If you land heel first all that preloading goes to waste very quick. A preloaded foot/leg is only useful if that load is transfered to the achilles/calve upon impact and during stance phase. If you land with a preloaded foot/leg on a big cushioned heel, the whole spring mechanism of the achilles doesn' come into action.
There is no such thing as a "midfoot" striker dammit, unless you have flat feet.

Yes! You could brake with a forefoot strike if you where over-striding for example.

Sure you can, even without flat feet. I just put a ruler down on the ground next to my average-arched feet. My feet are 11 inches long. My lateral arch, which you seem to be implying is midfoot is a bit off the ground. But its location is about 2.5 to 4.5 inches from the back of the heel. 5.5 inches is within the meaty portion of the lateral portion of my foot from 4.5 to 7.5 inches from the back of my heel, between the lateral arch and the base of my pinky toe, where I often land. I land with a variety of footstrikes depending on speed, grade, acceleration/deceleration, etc., but mostly midfoot.
Add - I know that landing on that meaty lateral portion of the foot is usually called forefoot, but the middle of the foot lengthwise includes that region. I also frequently land with that portion of the foot and the heel simultaneously, which a lot of people call midfoot.
It still loads the quads and the Achilles still has a spring mechanism as the knee breaks forward on landing and the foot remains flat on the ground as the Achilles is loaded.
How your foot strikes isn't really that important at all, it's about where it lands.
Say I heel strike, but my foot lands underneath the central mass of my body, then not really any harm is done. People don't realize that landing on your heal isn't that big of a deal, most professional runners do it in training, and some even do it when going fast (races). But, most professional runners' feet land under their central mass of their body so they don't get many problems if any at all.
I have found this to be correct for myself as well. My form is best when I land directly underneath my pelvis.

No, most of them still land slightly ahead of their central mass and you probably do as well.
Watch some video and freeze where the foot touches down.
Didn't Infeld just win the only US distance medal at worlds with a heel strike?
I was a sprinter in high school, and I never realized that some people heel strike until my 20's. I thought it was ludicrous. All I could imagine was my teeth clacking together with each stride.
