Welcome to the US. 2 weeks is common for lower end jobs. 3 weeks is typical for professionals starting a new job. I receive 5 weeks, plus 2 for sick time, and peers at other companies are astounded by it. I've also been at my employer for 10 years - I started at 3 weeks.

Of course, my Scottish relatives think it's completely normal. And I tend to agree. With only 3 weeks of leave, it's really hard to take 2 weeks off in a block. And I find a 2 week vacation is really required to relax and let go of work.
