I don't understand how this argument keeps coming up. If you use rails, schema changes and migrations are DEAD EASY and I am not even a professional developer. What time exactly are you saving ??

Schema changes are not dead easy when you have hundreds of millions of rows and/or hundreds of GBs of data.
