No, its not.
The default assumption of Rolemaster is that your character starts off as a zero and will automatically grow in power as you level albeit slowly.
In M&M, the assumption is that you set the power level based upon the type of campaign you want to run (e.g., street (6), New Mutants (6-8), X-men (10-12), Avenger (12), Cosmic). Despite min-maxers that ignore it and try to max everything at the PL, the power level of the M&M campaign, is still designed to allow you to have a diversity of power levels among the individual characters from the start. Furthermore, the starting points per power level in M&M are suggestions. The GM is given permission to provide more or less starting points than the recommended depending upon how experienced the starting characters are for their power level. Newbie heroes in a PL 10 campaign may have the starting points recommended for PL 6 or 8 while experienced heroes in a PL 6 campaign might have the starting points recommended for PL 8.
I would just like to point out that you said, "No, it is not," then said a number of things I know and don't disagree with. It is one thing to disagree with my interpretation, another to actually disprove it. I wonder if it might not have been more productive to say, "This is how I see things," and then provided some points to support your point of view. As it is, you have simply restated that in M&M and RM both, you receive a number of points per level to spend, which is my point. RM does not have optional rules to increase or decrease those points, of course.
