I think it really depends on the person. It depends on age, weight, height,arm length, amount of time you have been working out, etc. I don't think it matters what the average person can do. Worry about yourself and the goals you want to achieve and don't worry about what others are doing.
That's the best post here, IMO.
Goals are fine, but they can lead people down the wrong roads.
Basically when you're young and you are concerned about your "max", you're in it for the wrong reasons. I was guilty of it, and I'll admit, occasionally I'll see what my max is just out of curiosity. It's bred into us with weight lifting, but it's not the healthiest idea for weight lifting. Unless you're a power lifter, of course.
With all of that being said- If you're doing 1.5X your weight you're sitting pretty. If you're doing 2X your weight then you're doing phenomenal.
To explain why I said what I said above real quick, though- When people max they tend to sacrifice their form and of course that can lead to injuries. I would much rather go a full year doing less weight with clean reps than lifting more and doing sloppy reps. That's because I've gone through my fair share of injuries and layoffs because of this exact stuff, though.
Work hard and have fun buddy
Edit: BTW, I'm 6'0" 160 lbs. and I rep 185 about 12 times. I haven't maxed in about a year and a half, so I can't give you a good number, but last time I maxed I did 240. Back then I think I was only repping 185 for about 7 or 8, though.
