It is not going to be temporary but it is not going to be forever neither. Why it can't be temporary?

Because, there is a crash every once in a while and recovering takes a long time and when that recovery is finally getting over there is another one and another one and it continues like that, so in theory one printing is temporary and inflation is temporary, if there is no more crash ever again there won't be any more inflation and we would have a great economy that has never seen before, economy is something that would grow and be awesome without crashes. Why it is not forever?

Because crashes can't happen forever, we can't continue to have crashes every once in a while and still survive, enough people get affected by the crashes that corporations will be looked at as the guilty eventually and there will be a government where its filled with people who got affected by these and will stop giving them bail outs, may take a long time but will happen.
