How can you relate the saying "Money can't buy happiness" to Gatsby's extravagant parties?

The saying "Money can't buy
happiness" has considerable bearing on 's as a whole, and this phrase
is especially interesting when one considers the extravagant partiesthrows. Gatsby hosts
luxurious parties that become premier social events among the posh residents of the East Egg
district. The lavish extravaganzas are noted for their excess and the sheer scale and quality of
his parties' supplies:

"At least once a fortnight a
corps of caterers came down with several hundred feet of canvas and enough colored lights to
make a Christmas tree of Gatsby's enormous garden....In the main hall a bar with a real brass
rail was set up, and stocked with gins and liquors and with cordials so long forgotten that most
of his female guests were too young to know one from another" (39-40).

Despite Gatsby's excessive generosity in throwing these parties,
nobody knows Gatsby personally. Fitzgerald writes, "People were not invited--they went
there" (41). Even though the guests enjoy themselves, Gatsby himself seems to derive no joy
from these parties. He makes no personal connections through these events, and is ultimately
unhappy despite his fabulous wealth. Indeed, Gatsby will never be happy and satisfied unless he
obtains his romanticized relationship with . Therefore, Gatsby proves the adage "Money
can't buy happiness."
