Does the financial industry wants to do American citizens a favor by providing options for saving for retirement? No. The financial industry wants its companies to not only stay in business but to profit as much as possible. And to that end, it sells products - investment opportunities - designed to enrich the companies and their shareholders. There's nothing wrong with this, because consumers will only buy products they need or desire enough. Companies will sell towards that need. And when only half of Americans have discovered retirement savings vehicles like 401(k) plans and IRAs, the industry will resign itself to doing a better job in explaining to the country why their products are needs, not wants.
Saving for retirement is important. For most people, stocks are the only investment type that can grow wealth quickly enough to provide the dream retirement so impressed upon Americans through media. It's risky, as recent would-be retirees have seen. Thanks to the cognitive dissonance resulting in the understanding that the promotion of retirement is a result of the financial industry trying to increase profits on a large scale rather than corporate concern for the well-being of a nation and the knowledge that Americans must do something drastic to save money in order to fulfill the dream of quitting work, some Americans choose to invest while others would sooner give away their firstborn rather than drink the financial industry's Kool-Aid.
LIMRA may be right - that most people who do not invest for retirement with 401(k) plans and IRAs have not done so because the industry's message hasn't successfully penetrated their consciousness. That may be due in part to a lack of education, but for others, it's a lack of faith and trust in the industry.
