Why does the 757 have such a great wake turbulence signature?

I heard in class today that a variant of the 75 has a much greater wake turbulence signature than most airliners... Why?
 
From what I understand it comes down to two words. Wing loading.

It's a sexy beast in performance terms but it's uneasy to followers low and slow. The only time I've ever been truly "thrown" was behind FDX 757 into MEM in a crj-200. 45 degree bank angle and an autopilot disconnect. With many years following MD-10/11's at 5 miles it never happened. Asked my father in law about it (MEM supervisor at the time) he confirmed it was 5 miles, but also confirmed our -1500 altitude and heading change as we reported.
 
The 1993 Westwind crash at SNA mentioned in the article, which killed top executives of the In n Out burger chain, was the event that finally led to the FAA looking deeply into the 757 and it's wake turbulence issues.
 
Worst and most common wake I used to get is behind an Airbus 320 Series. Not that its worse than the 757 but it seems to throw out the largest wake in the Non Heavy weight class.

I find it's on the weight on wheels switch on anything "heavy". As soon as the wings flex... there they are.

We had chemtrails going on the ground 2 days ago! I didn't even know they installed the sprayers on my airplane. Mysteriously they were gone today.
 
In the In n' Out SNA accident the 757 was kept high by ATC so the wake turbulence was descending into their flight path. Those killed in the accident were company executives but In n' Out is a family owned business so most were members of the family.

Impact was near the 55 fwy at McFadden for those who know the area.

Wasn't that the second accident for that family? I vaguely remember them having another one where they left Aspen or Telluride where the pilot choked the pistons in the barrels because he didn't let it warm up before takeoff.
