I suppose we have to decide as a society how much help do we
want to extend to these unfortunate ones, and more importanly how
much of a safety net do we want in our society ? Obviously a social
security system a la USA is out of question, certain groups of
people in Singapore may simply choose to leach off society then, as
they do over here, able bodied people most of them, if millions of
Americans are on welfare because they can't find a job, how do you
explain the millions of illegals who sneak into the country for the
jobs that they couldn't find enough workers for then ? ...
and of course, such huge social spending comes with a heavy cost,
would you be willing to pay 40% income tax ? ... or 14% sales tax ?
(7% GST, 7% PST) .... that's what I'm paying now ..... to feed a
bunch of "society's unfortunate", some of whom live in the same
apartment block as i do, spending their days drinking coffee at the
cafe across the road ... able bodied all ... 
at the risk of sounding cynical, we do have to realise that no
matter how successful or wealthy a society is, there will always be
failures in the society, this, is simple social dynamics, for
certain issues, there's only so much we can do as a society, we can
legislate laws to enable parents to sue their children for support,
but we can't prevent children from abandoning hapless old folks,
there's nothing we can do to ensure that no lame and maimed exist
in a society (unless you're Hitler !) ... Frankly, though, i'm not
quite sure if there's a root solution to this issue. What do you
guys think ? ...
