The Industrial Revolution is a very large, complicated suite of changes. If we hold as a spectrum capitalism in one direction and mercantilism in the other direction, on a single line ( for simplicity's sake ) then most of the excesses attributed to capitalism begin to look more like mercantilism than actual capitalism.
People like Henry Frick just didn't know any better because it was all new.
Capitalism works well at eliminating production as a bottleneck. The rest is up to us. There's generally another bottleneck. Much of the 20th Century was about logistics.
But it's sort of dangerous to say that "capitalism was limited" - the thing that limits capitalism is economic busts. It's dangerous for two reasons. One, it's extremely hard to do at all, much less well, and two, you have to ask yourself if it ever actually was done to start with.
Peter Whybrow has a very good presentation on one of the CSPANs using Adam Smith as a yardstick for what may be wrong with capitalism today.
