The tax advantages of insurance are only good if you have gains and a significant accumulation of money. If you have Term Life Insurance, all those tax-free loans, tax-free withdrawals, and tax-deferred earnings are of no use because Term has no cash. For those with Permanent Life Insurance, if you have little money in it, it also makes little difference.
In reality, many policy owners either don't understand the advantages, don't have the money, or don't want to contribute enough to capitalize on the tax advantages.
In the past, traditional policies with low rates of interest did not help to accumulate high cash values, so these advantages were not so beneficial. But with the recent introduction of different savings and investment choices, more people are able to get better cash accumulation and make good use of these tax advantages.
Considering the amount of taxes people pay, people must understand and look for the vehicles, whether in insurance or investment, that can save their future cash build up.
