People like to see the big numbers, thats what draws the crowd! Thats also why you dont see many raw federations... who needs a whole federation of guys lifting what you can go into the local gym and see someone lift?
Track and Field has advanced because of better implements, so has skiing and pretty much any sport you can think of. Who would want to go back to the days when football players wore leather helmets and played a very dull, tedious game? No one.
There will always be "purists" who want things the way they were, but powerlifting is just like any other sport... advances in equipment make it more of a draw to a crowd.
Natural bodybuilding will never be that big for the same reasons... Aside from the people who are lying what do you have? Some 165lb guy thats ripped? Ive seen crackheads that size who are ripped, and Im not paying $25 + to get into a show to see them.
Powerlifting is the same way. People want to see something impressive.
The gear is difficult to learn to use, and is a skill unto itself. Most people arent going to bench 450 raw and get 600 in a shirt, most people might get 50lbs out of their shirt. The people making the big numbers in gear are like artists who have developed their skill at using the tool. Its not pretending. No one is saying that this is their raw weight. They compete in a federation that uses the gear, and that is their record.
Ive never heard a lifter who uses equipment knock a raw lifter for lifting raw, but the first thing you hear out of a raw lifters mouth when someone mentions a record is "I could do that if I wore all that gear!"
All that does is belittle raw lifting and make it seem subpar.
I used to lift raw. Now I enjoy the challange of learning to use my gear... and I'll take my "fake" 800lb squat over the next guys raw 550 any day. But thats just me... we actually train a couple of raw lifters and they have my full repect.
