The idea of philanthropy is a prerogative you may wield if you have the means and the inclination. It is not the government's job to extract charity or sacrifice from you by means of force, even if they are democratic or arbitrary about it.
The laws are not as plain.
The constitution says representation and income tax shall be apportioned, not collected according non-apportionment (democracy or political whim or statist mandate or bank fiat).
Apportionment means Congress is supposed to take a census, set up a budget and divide it equally amongst the inhabitants (excluding slaves taxed as 3/5 of a person and Indians not taxed as they are of foreign nations). The 13th amendment abolished slavery.
The 14th amendment gave free non-inhabitants the right to attain citizenship under residency, and the right to due process under the law although not the same dejure status of the FREE BORN OF STATES.
15th amendment gave voting rights to resident citizens which could no longer be withheld due to race, color or previous conditions of servitude.(Women were excluded from sufferage till 19th amendment).
The 16th amendment said "Congress shall have the power to tax all incomes without regards to the origin of the income." It is assessed in a non-apportioned manner on residents (everybody treated as a resident for tax purposes) by jurisdiction and contract where they either never were free born of one of the states or have submitted knowing and intelligent waivers to such inhabitant status (such as by agreeing under residency rules to: "abide by all the rules of the bank" when getting a bank account or receiving some benefit under residency or by having their mail sent to their "residence" instead of a post office box). Prima Fascia proof of residency along with contract to a bank under residency rules places one under the 16th amendment arrangement for non-apportioned tax obligations...... in MY VIEW.
In law, excluding some influence of contract or jurisdiction or both, the words income and wage are separate with separate meanings and so are the words resident (debtor- owing their citizenship to 14th amendment, an act of Congress) and inhabitant (creditor, someone to whom a debt is owed- a peer of any in political power who took such a vocation by volition- to serve the people as representatives.)
