It obviously is class envy, as your quotation proves.
Here:
With the enactment of the Income Tax Law of 1913, the Federal Government began to apply effectively the widely accepted principle that taxes should be levied in proportion to ability to pay and in proportion to the benefits received. Income was wisely chosen as the measure of benefits and of ability to pay. This was, and still is, a wholesome guide for national policy. It should be retained as the governing principle of Federal taxation. The use of other forms of taxes is often justifiable, particularly for temporary periods; but taxation according to income is the most effective instrument yet devised to obtain just contribution from those best able to bear it and to avoid placing onerous burdens upon the mass of our people.
Note that INCOME is considered the right thing to tax. Never mind that it isn't, that taxing income discourages its formation. But we'll let that slide.
Now on to inheritance:
ummmm, yes, it is an INCOME TAX.....that was established long before fdr and ALL thought it was JUST....to be taxed according to your ability to pay....this was not considered UNJUST, but JUST.
I My first proposal, in line with this broad policy, has to do with inheritances and gifts. The transmission from generation to generation of vast fortunes by will, inheritance, or gift is not consistent with the ideals and sentiments of the American people.
The desire to provide security for oneself and one's family is natural and wholesome, but it is adequately served by a reasonable inheritance. Great accumulations of wealth cannot be justified on the basis of personal and family security. In the last analysis such accumulations amount to the perpetuation of great and undesirable concentration of control in a relatively few individuals over the employment and welfare of many, many others.
Such inherited economic power is as inconsistent with the ideals of this generation as inherited political power was inconsistent with the ideals of the generation which established our Government.
Note that the tax is not justified as a means to raise revenue. It is not justified as anything other than a desire to stick it to people who have become wealthy through their own hard work and desire, naturally, to leave it to their children.
In any case, nature takes its toll on inherited wealth. Look at the great fortunes that were around in 1900 and see where they are now. Go back to 1800 and the numbers are even starker.
There is no "vast transfer of fortune from generation to generation." This is a lie.
