Ed Katz has maxed out his annual 401(k) contributions for nearly three decades.
While Katz, a software engineer, has had a six-figure salary since the late 1990s, he first started making the maximum contributions at the age of 35 when the federally allowed limit represented "well over" 15% of his salary.
"[I] said, 'Why wouldn't I do this? You just learn to live on less," said Katz. "I would do more if the government would let me."
He, too, sticks index funds, the majority of which are in equities.
