It seems that they both are right in a sense. Overindulgence of the self (Huxley) leads to destruction while overindulgence of Others (Orwell) does the same. Indulging in the personal pleasures leads people to forget about everything else while trying to take care of others too much leads to trying to run their lives when they don't listen to you even though you think you are right.
The only example I can think of is the way the Party controls the Proles - by making sure they have plenty gin, beer, porn, trashy novels and gambling. Which was presumably based on the observations of working class life he did for "The Road to Wigan Pier".
