Hey Devarsh, thanks for writing in and I appreciate you coming back to this story even after such a long time!
I actually wrote a piece about inflation, expenses and the SNP500. You can find it here. https://medium.com/datadriveninvestor/how-much-and-how-long-should-you-invest-to-retire-early-814df55e2c41
I am also working on another piece to further explain inflation actually. Hope it helps!
