Thanks for the comparative effort displayed in your disagreement with the link.
I really haven't been to the US or know much about their tax systems, though it seems that every state has a different policy, so it would probably be very hard to do a proper comparison, it seems?
Re cars: as mentioned earlier, everyone will have a different opinion on this. I personally haven't had a need for a car. It would definitely be very convenient but I don't think it should be viewed as a de facto must-have? So I have to disagree with you that leaving out the price of cars is unrealistic.
Re tax: It is ok if you don't know. I am telling you now. I was living in California, with one of the highest state tax rates. Federal tax is the same within all states of USA. So it is possible to get even lower tax rates than what I experienced. Like Texas for example, there is no state tax at all.
Re cars: you personally do not need one, doesn't mean everyone doesn't need one. Especially folks with children and older folk.
So what about housing? Electricity? GST? GST hits the mid to low income folks the most. Because it is not based on income level. And for people making less, the sales tax of necessities (both products and services) the percentage is so much larger than high income individuals.
Pricing of healthcare is also starting to skyrocket. in 2013 alone, a doctor's visit at TTSH has gone up more than 30% hike. while service levels have dropped, very long wait times. Even the wait at the pharmacy is now as long as 1 hour at times (my max wait was 2 hours). My mom had to go for an op, and the next available appointment in 9 months. And doc says although her condition needs surgery soon, there is nothing they can do with dates. They "strongly" recommend that my mom go see private practice to get it sorted out. Which we did in the end.
And as for polyclinic dental, the next appointment waiting list is more than 12 months.
All I can say are the things I experienced. Each and everyone should come to their own conclusions. I have mine.
Of course, There are also many who are very supportive of the current status quo, a big fraction of them are probably people who benefit the most from how the current things are being run.

Sometimes, if people never lived overseas, they really do not know that at times, the grass is indeed greener on the other side.
