Tobin Tax - another window tax?

One could argue that the Financial Transaction Tax (aka Tobin Tax) is nothing to get excited about, there are taxes on air tickets, house purchases for example. But there also once has a tax on the size/number of windows in some countries. All taxes on specific transactions are questionable as there is not much logic that supports them and they are easily abused in the politician's neverending quest to finance ever-more ambitious spending plans. Most of these taxes lack a proper democratic mandate and they are highly discriminatory and arbitrary.
