I think there's less ageism in Europe - I'm German and in Germany and I don't hear the same stories as on HN about that. Pay is lower, though.
Maybe lower pay but you don't have to pay for healthcare there right?
My salary works out to roughly $120 per hour. I pay a $15 premium to insurance from each paycheck and a $20 fee to see a doctor. Even if I had some catastrophic car crash and spent months in the ICU, my maximum annual payment for all healthcare is capped at $5,000.
Healthcare costs can be a huge burden for low and middle-income Americans, but for a senior tech worker, healthcare is a tiny expense compared to income.
