I have a degree in music, so obviously I like numbers. (What? Music is math.)
Suppose you had ten million dollars. Suppose you invested that ten million dollars in such a way that you could guarantee a return of ten percent per year. That's a reasonable rate of return, producing a million dollars, before taxes.
Let's take off 40% for taxes. Now you have $600,000 coming in every year.
Suppose you hired 5 programmers at $90k annually. They can work from home, so $90k is a solid developer salary in the US for anywhere but Silicon Valley or New York City. Suppose you spent the other $30k for administrative expenses, including insurance and 401(k).
What could you do with five full-time developers? (That's an order of magnitude more paid full-time developers than Parrot and Perl 6 have, combined.)
