I'm not sure, where are you getting those figures from? I can't find solid figures for either but the rough figures (guesstimates) I come across seem to indicate time theft is a larger problem than wage theft.

These are estimates. You can also find estimates for time theft in the same ballpark. Solid figures are much lower —estimates are higher as they have to extrapolate into areas with little data.
