Unsurprisingly, the ratio has been going up.

For 2001 and 2002, it went down - no doubt due to tech bubble bursting losses offsetting.

The question is - where is it now?

It would not surprise me if we were in the 15%+ range now.

Which, if true, would make the ongoing capital gains reductions an ever bigger farce.

Note: other data shows the peak in 2000 was 12.8%
