vacation time around the world

now that the vacation time is over for most folks, it's time to start complaining how short our vacation is.
i came across a chart of 'minimum vacation time around the world' in wikipedia. interestingly, united states seems to have the one of the lowest number of vacation days. seems to me that those complaining of chinese labor practice in the united states should concentrate their efforts in helping united states catch up to the rest of developed world first.
