This coin has a very big supply and very big annual inflation. There is no way of reaching $1 in our lifetime.
Well, never say never, Korea could blow the USA out of the water and then the dollar would become worth next to nothing and 1 doge might just be $1. Also a BTC would be about $100m 
but other than some ridiculous fall in value of the dollar as described then yes I agree it will never happen, the supply is to big.
