I pointed out that more money is needed for the poor.
Literal
Poor people [for-ために] more money [subject-が] necessary [copula-である] thing [object-を] I [topic-は] pointed-out.
指摘した means 'pointed out.' The embedded clause 貧しい人たちのために、もっとお金が必要であること nominalizes a full statement with こと. のために here is purposive ('for the sake of'), not causal.
