As someone in the US, 40 hours per week is the minimum. Recognition for "being a hard worker" has required 60+ hours at some places I've worked. This is for a fixed salary and no overtime pay, mind you. Then you're usually on an on call rotation every few weeks where you may have to work off-hours if something comes up. That's additional unpaid hours. My current company pays $80,000 USD for new college grad software developers.

US holidays are 8-10 days, and junior devs usually start with 5-10 days of vacation. Health insurance costs at least several hundred a month (your employer also pays about 3x more than you towards your insurance premium as a benefit).
