Tax Planning is an integral tool for investment purposes.

The typical revocable living trust wherein the trustors are the lifetime beneficiaries and retain the power to revoke,
amend and invade the principal of the trust provides no protection whatsoever against the creditors of the trustors.
It is not always necessary that you are wealthier to pay this 
tax, if you can, why cannot save your precious money if you can simply do that with 
proper inheritance tax planning.
