I acknowledge there's a problem with the current grading system, yet I am still convinced that grades are correlated with one's aptitude/intelligence. In my personal experience though, I only noticed the inflated grades problem in the US. While I was an undergrad engineering student in Spain there were some classes where not even 50% of the students passed, and overall, only 5% of them graduated with the minimum amount of time (5 years). On the other hand, when pursuing graduate studies in the US, not only were the classes easier, but in many of them most people got A's. In my opinion, that defeats the purpose of grading.
