If the radiocarbon system was flawed, why would it ever match the rate of tree ring growth? Not to mention that while it's a common means, it's not the only means. Varve layers from lakes work, too, as do recently formed carbonate deposits. These and other techniques can be used to cross check, and they match up.
It would match up because they calibrate off each other. And these systems can be proven only so long as there is an history of using them. When you begin to assign dates that are far older, you assign them with the assumption that the decay/deposit/growth rate stays the same over that length of time.
