Employees operate within the rules established by their employers - they have a boss and are expected to be a "good solider" to support objectives of their company / business unit... People like Steve Jobs are successful because of their audacity to disregard the rules and make their own.
These are entirely different mindsets and skillsets. Employees are given direction, entrepreneurs set the direction.
What I find a lot more interesting is that quite a few startup founders act like employees rather than leaders - constantly asking (explicitly or implicitly) for approval of others. Look around and see if you can recognize people who care about the opinions of press/investors/advisors/peers more than achieving product/market fit followed by revenue/profitability/growth.
