First, I'd say you can always find some schools where it is easier to get A's than it was. But it probably isn't a trend.
Second, if it is a trend, do not blame the teachers. This is an administrators' issue. At my University (where I teach and TA), there is a huge push to increase graduation rates. Sounds great, since graduation rate is a huge problem where diversity is high and support is low. Unfortunately, the easiest way to get X students / year is to "lower the bar."
However, the teachers always fight back against this. In general, the average graduating student with a decent GPA is in fact a good representation of what we want a student to look like. So, thanks in part to the tenure system (in which curmudgeonly teachers can't be ousted by angry administrators), we still have high standards for our honor students.
