In an objectivist society, would hard work reliably translate into financial success?

One thing I keep thinking about as I explore Rand and Objectivism is this in a truly laissez faire system, would people who work harder actually outperform their peers financially? On one hand, it seems intuitive, more effort, more output, more value created. But in the real world, outcomes don’t always line up that cleanly. Timing, market demand, leverage, and even luck seem to play a role. So I’m trying to understand how Objectivism views this Is hard work alone enough, or does it have to be paired with the right kind of work? How does the philosophy account for differences in opportunity or starting point? Would a fully free market naturally align effort with reward over time, or is that an oversimplification? I lean toward capitalism because it seems to reward value creation more than alternativebut I’m not convinced it’s as straightforward as “work harder = earn more.
