>Why would I volunteer to take on a crummy or particularly hard task when I can
just hope someone else does it and I reap the rewards?
When you are on a team that is committed to the success of a project or a real thing in the world, rather than hoping for a bonus, you help everyone on the team at each step of the process. If you enjoy the work you are doing, you'll enjoy the hard tasks; even the tedious tasks take on a certain type of satisfaction in a good job.
A team where people are sitting around for others to take action is not a good team or a good job. I encourage you to raise your standards.
>Rewarding individuals based on the group outcome is a great way to drive rockstars away from the team.
I don't care how many rockstars are on a team, I care if the team is transforming the world into a better place, is helping the company and humanity make the transition to "everything is software and networked" a thrilling transition. If someone is slower mentally but has a vision of a better world that the team is making happen, then they will probably move the team towards delivering on that vision than some smart but Blind obsessed person that wants the "FIRE" crap. Also, valuing money over all means your team will fall into traps like accounting irregularities more easily - lacking a sense of values outside of economic gain means the team will fall into things like the Enron mess or https://www.washingtonpost.com/archive/business/2005/03/22/t... or the various shady ad selling schemes or privacy selling schemes so common these days.
I've worked with teams where most people love the work and love the outcome of the work on the world, and I've worked where people are beset with visions of becoming some sort of rich software engineering lord, and it's a lot more fun in the former case.
People that want families and is supporting them are not doing software only for a princely salary. The thing that's awesome about a software career and families is that the demand for engineers means you can afford to insist on the flexibility and time-off needed by the family, and still get a livable salary.
