Yes, but I'm not going to write a textbook for you, here is one good and impartial link to explain some of the basic economics behind the issue with facts:

What a poorly written piece. First of all, in the "extreme cases" we already know the tax rate is not optimal and has to be somewhere in between, so the extreme cases in fact do not tell us anything useful (both give very poor results and are unsustainable).
"If such a society were possible, we can see that people would be quite productive as any income they earn, they keep. " Is that the only thing determining productivity? What about education? You know, that stuff you fund from tax dollars. Don't collect enough taxes to educate the lower classes, and their productivity is going to take a nosedive.
"Do you think he'll spend more time at work or less if his take home pay is $8.00 rather than $2.00? I'd bet you that at $2.00 he's not going to spend a lot of time at work and he is going to spend a lot of time trying to earn a living away from the prying eyes of government." Well, I don't know. There isn't actually a country that taxes so heavily. We do know, however, that employment rates are very high in the current high taxing countries, so a tax rate of 50-60% does not appear to impact the willingness to go to work significantly. In fact, here in the Netherlands, where the top income tax bracket is 52%, unemployment is lowest of the EU.
"Government tax revenue does not necessarily increase as the tax rate increases. The government will earn more tax income at 1% rate than at 0%, but they will not earn more at 100% than they will at 10%, due to the disincentives high tax rates cause. Thus there is a peak tax rate where government revenue is highest. The relationship between income tax rates and government revenue can be graphed on something called a Laffer Curve. " But the Laffer curve does not tell us anything about where the optimum tax rate is. For all we know, it might be 90% (probably not true, but the Laffer curve cannot be used to disprove that statement).
