"' improving the lot of the poor, but firmly entrenching the aristocracy in power, gave Athens some stability.""

Firstly, why is your hidden comment in the middle of a sentence? What exactly'' are you objecting to?
Secondly, why so patronising? You can just disagree with the statement. There's no need to make pithy comments about 'grade school' - which are also completely inappropriate, since that was not written by someone who is in 'grade school', whatever that is.
Thirdly, if you disagree with it, why not change it yourself? If you know that this is a misrepresentation of the historical record, then you obviously know how it could be re-written. So just do it instead of carping on about 'grade school'.
Fourthly, try to summarise the Athenian land crisis and its resolution in four sentences, in a way suitable for a summary style article. You'll find that there really isn't space to revise it to a current level of understanding.
Fifthly, why not use the talk pages to discuss articles? That's what they are there for.
