for many people, the proper strategy is to strip the parents of assets so they qualify for medicaid to pay for nursing/medical care, otherwise the govt. requires the elderly to spend all their assets first.
also, some people need to get under the 2 million inheritance tax cap which means over 2 mil and the feds take 50% the state and attorneys also get their cut.
That's not a "proper" strategy, it's a dishonest and unethical strategy.
