Yeah, you can get into other fancy tricks to defend it like:
Input-specific technological progress. Even if labour has grown more slowly than capital, maybe the ‘effective labour supply’—which includes tech makes labour more productive (e.g. drinking caffeine, writing faster on a laptop) -- has grown as fast as capital.
Input-specific ‘stepping on toes’ adjustments. If capital grows at 10%/year and labour grows at 5%/year, but (effective labour) = labour^0.5, and (effective capital)=capital, then the growth rates of effective labour and effective capital are equal
