If you look at the demographics that make up the U.S. grunt, it's pretty plain to see they're stocked with minorities and lower class.
When not in a time of war, enlisting for these (and many other) young men and women is a REALLY good option. You get paid, job training, learn discipline and respect, get money for college, and in the vast majority of cases an honorable discharge.
It gets them out of the ghetto/trailer park and into a real job or college and then a real job via the G.I. Bill. In a world where EVERY
country and EVERY
individual is ultimately looking out for number one, I can't blame the kids out of high school with no other options for enlisting.
I can blame the military recruiters and commercials for some pretty predatory tactics in their search for more bullet-catchers, but 9 times out of 10 the PFC or Corporal discharged from the military is much more likely to be a productive member of society than his peer who stayed at home and is now living on the streets.
And as for the ideology of the U.S. culture giving rise to wars or being extra aggressive or something like that, I once again quote the boomer bible:

3 But this is a lie which you have made up for yourselves, because you are not very smart and cannot think of any other way to look at it.
4 The truth is that all trees are of the same tree,
5 Which is the tree of Mankind,
6 And one is not different from the other in its basic nature.
7 You would revile the conquistadors because they committed genocide in the name of God against the Mayas and the Aztecs,
8 But I ask you, Did not the Mayas and the Aztecs also commit genocide in the name of God against those who opposed them, and even against their own people?
9 You would deplore the Brits who committed genocide against the Zulus of South Africa, not even in the name of God, but in the name of the king, for the purpose of expanding their evil empire.
10 But again I ask you, Did not the Zulus commit genocide against their neighbors, also in the name of their king, for the purpose of expanding their empire?
11 And so what is the difference between the conquistadors and the Mayas, or between the Brits and the Zulus?
12 The only difference is that the Spic tree was taller than the Maya tree, and the Brit tree was taller than the Zulu tree,
13 Just as the American tree is taller than the tree of Southeast Asia or the tree of the native Americans.
14 And if you cut down the biggest tree, you will simply make room for the smaller trees to grow taller,
15 By committing genocide against their neighbors and their own peoples,
16 Which is what they all want to do anyway,
17 All of them,
18 Including even the very tiniest trees on the planet,
19 Even unto the headhunters of the rain forest,
20 Who have no nuclear weapons,
21 Or B-52s,
22 Or napalm,
23 But still want more heads anyway,
24 Because they too are of the tree of man.
Moral of the story: This is about as American a phenomenon as falafels. It's a human condition, not an American condition. Your country is no better or worse than America. And you are no better or worse than Americans. Because, rest assured, the big ones will ALWAYS push around the little ones - even your own perfect home countries are pushing a little guy around as we speak.
