This is true.....................

...................regardless of what country you live in:

The drive for change comes from two sources, one foolish, the other discreditable. The foolish idea is that you should aim to create the appearance of progressivity, not just in the tax system as a whole, but in every part of it — an idea which has added much avoidable complexity to the tax system in the past two decades. And the discreditable idea is that if you fiddle with the rules to raise more revenue now, the consequences will be a matter not for you but for your successors.

-John Kay, as excerpted from here
