Actually we do get paid holidays
Umm... sort of... in 9 of my 10 years working experience, I didn't get any holidays off. I did get paid double for working those days, but the company had a bunch of fine print that would allow them to deny that extra pay if you screwed up in any way, such as showing up late, not meeting productivity quota, etc the day before or after the holiday. I don't think the majority of Americans deal with that kind of thing, but I don't think it's exactly uncommon, either.
There's also only a handful of countries in the entire world that don't guarantee paid vacation time or maternity leave, and the U.S. is one of them.
The way our workers are treated and our general quality of life is godawfully abysmal compared to the rest of the world.
do have mass transit (just not across the whole country)
Which is a barely functional joke just about everywhere save a select few cities.
Anyway, I don't think America's worst problem is apathy. I think it's that we're so divided. We have to deconstruct and culturally immunize ourselves against the way our politics and media pit the population against itself before we'll ever be able to challenge the authoritarian corruption that plagues us.
Right now, we can't even deal with the insanely obvious good cop-bad cop/lesser of two evils tactic that keeps us stuck with two parties that cooperate with each other to prevent any challenges to their combined political dominance and both agree on supporting and escalating the police/surveillance state, environmental destruction, rising inequality, and the emerging corporate feudalist cyberpunk dystopia that America is in general.
And a not insignificant second factor is that everyone's too busy trying to keep up with their working lives and make ends meet day to day to engage in building a better future. This is why activism is stereotyped as dominated by young white kids, because they're the only people that have the time and freedom to bother. Everyone else only gets a couple hours a day at most to themselves (which they spend dealing with their exhaustion), and their lives fall apart very quickly if they don't tend to the responsibilities that dominate the rest of their day. Anyone who isn't living like this is generally either in the privileged minority, or of some class that is kept marginalized by the overwhelming and brutal police state.
