VOO versus SCHD. Why voo?

Hi all,

I have about 50k in VOO right now and I am thinking of putting this all in SCHD. I am nervous about this but I would like to ask for those who invest in VOO and think this is a better investment over SCHD because of better total returns, why else do you invest in it? Aren't you scared of putting your retirement funds in the market only to go through a lost decade for when you might retire? This haunts me! SCHD on the other will generate consistent higher cash flow/dividends regardless
