"The success of philanthropy will always be limited. Why? For one thing, neither money nor a good secular education caneliminate such problems as greed, hatred, prejudice and false religious beliefs. Accordingly, rather than
set up philanthropic organizations, Jehovah's Witnesses prefer to devote their time and financial resources to
announcing the good news of God's Kingdom."
That's a false dichotomy, claiming that because philanthropy cannot eliminate such problems, that it is therefore limited. No problems can be totally eliminated, but they can be lessened greatly. Good secular education allows a person to find better work and earn enough to be around other people who've also done well for themselves. Without such education, you'll be stuck earning less and living amongst poorer people, who might be on government dole, and therefore no incentive to work. People who aren't trying to better themselves eventually exhibit signs of predjudice, greed, and hatred.
