Back in the day, retirement planning was much simpler. Your parents and grandparents usually worked for the same company for their whole careers, and were paid a pension when they retired. The pension (benefits) continued to provide an income for them each year, no matter how long they lived.
However, pension plans are rare in today’s private sector. Retirement planning has shifted from being the employers’ responsibility to falling on the shoulders of employees. Needless to say, many workers are looking for ways to reproduce the annual stream of income that standard pensions gave them — without the concern of being cash-strapped in retirement. For these people, annuities are an excellent option.
