It's probably important to note the Netherlands has a high degree of decommodification (i.e. a lot of state provisions), with the US having some of the lowest in the developed world.
The result of that is that distributive justice is a lot stronger, and the impact of a regressive tax system is magnified. A median salary in the US might generate unsatisfactory, whereas in the Netherlands even a below-median salary has quite good outcomes because of this.
For example, the median healthcare insurance expenditure in the Netherlands is about $1.5k a year, and healthcare outcomes are quite good. Tuition fees in university for undergrad and graduate degrees are about $2.5k a year across the board, with a tiny fraction of students being the exception like dental or piloting schools. Student loans are currently at 0% and set to go to 1% next year. Tuition-waving subsidies exist for children of poor parents. Childcare is heavily subsidised. Traffic policy and public infrastructure is such that a car is not necessary, and employers tend to reimburse all public transportation costs for most employees. Lastly, it just feels like culturally the Netherlands is slightly more sensible with its consumerism and interest in toys. Most seems to be spent on things with higher lifetime values, meaning the effective value of money seems to do a bit better, but that's just intuition from anecdotes.
In short, when you get your after-tax income, you tend to be able to spend a very large portion of it on things you don't really need, but just enjoy. Nice food, vacations, hobbies. There just isn't an need for a $100k salary for your kids to go to a nice school, have childcare or a good insurance, or a car to get your family places. Nor do you need $100k to cover interest payments + principal on 6% student debt of $100k.
That having been said, your numbers on Asian/Australian vacations definitely cater to a certain tourist. I've done a month in Asia on 1k, but I was 19. Similarly I could do 3k in Australia, but I'd be a certain kind of vacation. You AirBnb and eat some simple Asian takeaway like food and travel by bus. That's not everyones idea of a holiday. It's a different vacation from getting taxis to hotels and eating in restaurants.
