That few people hate Americans is true, but the sheer volume of their cultural exports means that half the world has a first impression of them - one usually provided from the Americans themselves, and rarely flattering. I don't think anyone would condemn the US purely over a few subjective cultural traits, but the political and economic trends that they impose on the rest of the world are certainly open for criticism.
I know that in my own country working hours have been getting longer, salaries have been shrinking, job security became non-existent, worker's rights are infringed upon daily, and a few dozen "entrepreneurs" have been reaping millions off of this (and none of them are "ingenious", but merely assertive, aggressive, and opportunistic). Everyone identifies this trend as "becoming more like America," and it's genuinely scary. It feels like the field is being rigged so that the unscrupulous get rich, and the rest are at a disadvantage.
A trend I'm personally freaked out by is the American disdain for the 40-hour work week. It's a sentiment that's slowly creeping all over the globe, essentially associating organized labour and labour rights with "laziness." It also sets up the assumption that everyone's life has to revolve around their jobs, and that everyone dreams to be a millionaire (which is untrue and, frankly, insulting).
