I am sure why people would be interested in having fixed income, not interested in having higher overall return. Focusing on overall return (dividend+growth) is the true return which can also be translated into higher income. Many seemingly high "yield" funds are more volatile and at the expense of NAV reduction.
(assuming you meant to say "not sure why")
Total Return was great during the acquisition phase of my financial life. Being a probabilistic method that offered higher expected return than anything deterministic, the issue was how long you would have to w*rk before attaining F.I. For me, things went better than expected so I was able to ER earlier than expected. If they did not, I just would have had to work longer to achieve the same standard of living in retirement.
In retirement, however, the downside to things not going as expected is higher. There aren't the do-overs analogous to working a few years longer like during the working years available in retirement.
I view the extra spending that I could forego by not running a total return strategy in retirement as purchasing relative certainty instead.
I watched my fathers standard of living decline in retirement for factors that were external to him. I would never want to be in that position.
Also one of the benefits of "over saving" is that in retirement I can spend whatever I want regardless of whether my spending in retirement relies on total return or more deterministic/income oriented sources.
It's worth mentioning that just because I am not pursuing a total return spending strategy
does not imply that I am 100% invested in income securities. Note I still have over 60% of my assets in broad stock index funds so I will be getting the market growth if/when it occurs.
With that growth I can purchase additional individual bonds or annuities or whatever to actually increase my deterministic income /spending ability if that is desired. The thing is that my quality of life does not depend on it.
I sleep better at night knowing all of this is in place.
