Was there happiness in "The Rocking-Horse Winner"?

Well, a quick look at the characters tells us there's
little or no happiness for anyone in this story.  Here we
go:

Father-- Married to a bitter wife who never has
enough--even when she gets more, it doesn't satisfy her.  She claims he's unlucky.  His
son dies.

Mother-- Has everything--house, servants, kids,
stables, clothes, and more--but it's not enough.  Bitter and discontent because she
feels she has no luck, despite the things she has, mentioned above.  Her son
dies.

Sister--  Has to also sense the throbbing financial
needs of the house and the bitterness of her mother.  Her brother
dies.

Uncle Oscar--Perhaps a little happy, since he did
make some significant money on the races; however, he also has to feel some guilt about
being somewhat responsible for his nephew's
death.

Bassett--The stable boy who gets Paul started on his
betting "career" has made a lot of money, so he is certainly happier.  However, he, too,
must feel some guilt regarding the boy's
death. 

Paul--Hears the cries of the house and longings of
his mother, understands that money is what will make her happy (because that's what she
says), then discovers money is not enough.  He, of course, dies trying to create more
money.  He tells his mother he's lucky, and there is apparently some truth to that--for
awhile.  He may have a moment or two of happiness in his life, like when he anonymously
gifts his mother with money, but it doesn't last.

Even the
house is not happy--

"And so the house came to be haunted by the
unspoken phrase: There must be more money!  There must be more
money!"

Paul's
mother says:

"If you're lucky you have money. That' s why it's
better to be born lucky than rich. If you're rich, you may lose your money. But if
you're lucky, you will always get more
money."

Apparently, then,
 Paul is lucky--but he's sure not happy.

One side note to
this story--some have interpreted this as a story of abuse by one or more family members
against the young boy.  If that happens to be your interpretation, I suppose we can say
that Paul is now happy, since he is free from such
torment.
