Yes, I agree; my children also get what I consider to be a lot of homework.
But it is reletive to the child and their abilities.
My 12 year old daughter is exceptionally brite and is in all advanced placements ( definite scholarship material) she handles all the homework, reports and projects in a snap! We are never concerned.
My 9 year old son, smart as a whip, would rather be out playing and requires constant supervision to complete assignments. This is a daily battle.
Yes, there is much homework. However, look at the enormous amount that this generation has to learn. There is global competition in everything, and they have more contend with ( on many levels) than our generation.
