I'd prefer to get away from the lathe example because it's not actually a great example of whats going on. I solely used it because the person I was responding to used it.

So back to software. If I have an idea for some company (lets say Twitter2.0) and I bring in ~10M in revenue from selling ad slots but I also paid a bunch of programmers ~8M over the course of the year and somehow the rest of overhead/expense was 1M. I think we can both agree 10M > 9M and so my business venture is profitable.

However, come end of year I have book 10M - (1M + 1.6M) = 7.4M of profit. You may wonder how I can book 7+M of profit when I spent 9M on 10M of revenue and this is exactly what this whole thread is about, programming salaries must be amortized.

This leads to the problem I have to pay taxes on 7.4M of profit using the 1M that I actually have left over so as long as the tax rate is below 13% there's no problem but if its any higher than I need to take out a loan to pay taxes.
