Labor Is Capital

As Robert A. Heinlein has succinctly stated:

Time is your total capital, and the minutes of your life are painfully few.

Don't take my word for this. Read what the Supreme Court says on the issue of "labor".

As in our intercourse with our fellow-men certain principles of morality are assumed to exist, without which society would be impossible, so certain inherent rights lie at the foundation of all action, and upon a recognition of them alone can free institutions be maintained. These inherent rights have never been more happily expressed than in the declaration of independence, that new evangel of liberty to the people: 'We hold these truths to be self-evident'- that is, so plain that their truth is recognized upon their mere statement- 'that all men are endowed'-not by edicts of emperors, or decrees of parliament, or acts of congress, but 'by their Creator with certain inalienable rights.'-that is, rights which cannot be bartered away, or given away, or taken away, except in punishment of crime- 'and that among these are life, liberty, and the pursuit of happiness; and to secure these'- not grant them, but secure them- 'governments are instituted among men, deriving their just powers from the consent of the governed.' Among these inalienable rights, as proclaimed in that great document, is the right of men to pursue their happiness, by which is meant the right to pursue any lawful business or vocation, in any manner not inconsistent with the equal rights of others, which may increase their prosperity or develop their faculties, so as to give to them their highest enjoyment. The common business and callings of life, the ordinary trades and pursuits, which are innocuous in themselves, and have been followed in all communities from time immemorial, must therefore be free in this country to all alike upon the same conditions. The right to pursue them, without let or hinderance, except that which is applied to all persons of the same age, sex, and condition, is a distinguishing privilege of citizens of the United States, and an essential element of that freedom which they claim as their birthright. It has been well said that
'the property which every man has is his own labor, as it is the original foundation of all other property, so it is the most sacred and inviolable. The patrimony of the poor man lies in the strength and dexterity of his own hands, and to hinder his employing this strength and dexterity in what manner he thinks proper, without injury to his neighbor, is a plain violation of this most sacred property. It is a manifest encroachment upon the just liberty both of the workman and of those who might be disposed to employ him. As it hinders the one from working at what he thinks proper, so it hinders the others from employing whom they think proper.' Smith, Wealth Nat. bk. 1, c. 10.
Butchers’ Union Co. v. Crescent City Co., 111 U.S. 746 (1884)
In our opinion that section [of the law in question], in the particular mentioned, is an invasion of the personal liberty, as well as of the right of property, guaranteed by that [5th] Amendment. Such liberty and right embrace the right to make contracts for the purchase of the labor of others, and equally the right to make contracts for the sale of one's own labor; each right, however, being subject to the fundamental condition that no contract, whatever its subject-matter, can be sustained which the law, upon reasonable grounds, forbids as inconsistent with the public interests, or as hurtful to the public order, or as detrimental to the common good.
[...]
The right to purchase or to sell labor is part of the liberty protected by this [14th] Amendment, unless there are circumstances which exclude the right.
[...]
In every case that  comes before this court, therefore, where legislation of this character is concerned, and where the protection of the Federal Constitution is sought, the question necessarily arises: Is this a fair, reasonable, and appropriate exercise of the police power of the state, or is it an unreasonable, unnecessary, and arbitrary interference with the right of the individual to his personal liberty or to enter into those contracts in relation to labor which may seem to him appropriate or necessary for the support of himself and his family? Of course, the liberty of contract relating to labor includes both parties to it. The one has as much right to purchase as the other to sell labor.'

Adair v. U S, 208 U.S. 161 (1908)
The principle is fundamental and vital. Included in the right of personal liberty and the right of private property-partaking of the nature of each- is the right to make contracts for the acquisition of property. Chief among such contracts is that of personal employment, by which labor and other services are exchanged for money or other forms of property. If this right be struck down or arbitrarily interfered with, there is a substantial impairment of liberty in the long-established constitutional sense. The right is as essential to the laborer as to the capitalist, to the poor as to the rich; for the vast majority of persons have no other honest way to begin to acquire property, save by working for money.

Coppage v. State of Kansas, 236 U.S. 1 (1915)
capital n. 2.a. Wealth in the form of money or property, used or accumulated in a business by a person, partnership, or corporation. b. Material wealth used or available for use in the production of more wealth. c. Human resources considered in terms of their contributions to an economy.
