But saying that 200 million and 30 are in the same ballpark is not true in 99.99% of contexts.

Even 50k and 30 I would not say are in the same ballpark. I've worked for major corps and of course a cost saving of 50k/month would not register for the overall company but it probably would for my team. A saving of 30/month is probably not worth spending any considerable amount of time on in most non-personal contexts.
