There is a statement about the need to get over oneself somewhere in there, but finding it is an exercise for the reader.
We may consider perhaps one can only truly earn $1M. But, what if someone has an idea that benefits a billion people to the value of a dollar each? You may not think, for instance, that Facebook in particular qualifies, but the point is, it seems to me possible in principle. Or, what if someone invents something that saves a million lives? You can't put a dollar amount on that, maybe, but surely it's worth more than $1M, because courts put that much value on just one life frequently.
All in all, the existing situation, where taxes are a percentage of what you make kind of makes sense to me. It is consistent with believing that living in society is a multiplier.
I remember reading about how Japan was desperate to increase inflation a bit and then they raised the VAT or something like that - and I was bewildered at why they were shocked that inflation promptly wilted further.
It's disheartening that you hear more about a national sales tax/VAT rather than trying to go in the other direction and eliminate sales taxes, not to mention making capital gains rates the same as all other income.
