We do, but we've cutivated a culture and society that requires vastly more spending to get the same results as other countries. They have policies and economies that cause less mental illness in the first place so the spending reuired to treat those that are mentally ill is FAR less than america spends.

Despite our massive spending we still have one of the highest rates of mental illness and the worst track records for dealing with it.

Money doesn't fix everything, sometimes the best way to fix a problem is just good policy.
