I use people I employ as my education

I usually assume a role like engineering manager and learn from the teams feedback, challenges and commits

Making money, getting tax deductions and sometimes research credits

If I may chime in here, I would humbly suggest that it is best done by whoever enjoys it.

Sometimes that might be your employee, and sometimes that might be you.

I guess it depends on where your passion lies, and what your objectives are?

I imagine that achieving one's financial ambitions in a relaxed and enjoyable work environment is great - irrespective of which part of the stack one enjoys tinkering with the most.
