No they are not useless 
As you can see, the figures between 1990 and 2000 don't have a
substiantial variation, or huge fluctuations(edit: cept maybe in
1997), cept maybe in year 1997. And my claim, which is based on the
figures from 1990 to 2000, and then plotting a graph in the same
trajectory till 2006, will only show that the median income going
up is mainly contributed by the higher income groups, as opposed to
a general across the board increase for singaporeans.
To lazy to read that thread, skimmed thru, hasn't it been
derailed either?
And I am not discussing the issue of a widening income gap per se,
although somewhat related, its the higher income group "pulling up"
the median and/or mean income figures.
Well you can claim my father is Gay, and I said, I don't know,
but I have never seen him screw or kiss a man, so based on that,
yeah he's not gay, and I'm apealing to you to prove otherwise
And PM Lee has never called me son either. That was just to humor
you 
What has been happening is that you have been dismissing some of
the facts that some other posters have presented, as
irrelevent/untrue etc.. but have yet to produce facts of your own
to counter them. Whether you are right or not, it gets them going.
