5th amendment is already in the Constitution.
Yes. It is.
But income you didn’t earn yet when something happened to prevent it or will not earn because of circumstances beyond your control is not actually your property because of the implied “yet” in the equation. No one is in arrears to you or anyone else because earnings fall short of expectations.
And here is something else to consider: when the federal prints up money the value for it comes from the wealth people already hold ... if you balk (and rightfully so) at the federal acting lawlessly to shut down the economy why give them a pass when they rob savers for their “gifts”. It’s like with social security: just because someone was defrauded of their means to provide others with unlawful benefits beforehand does that give them the right to demand others be similarly defrauded so that they too may later receive their illegitimate benefits?
Moreover, there is no delegated power in the Constitution to spend money on individual welfare just because they are here (which is distinct from something because of current or previous service) or their lot was somehow affected by government actions no matter how desperate that person’s straights may be. Same with the welfare of communities or even whole states (why I oppose federal disaster welfare ... er, “relief”).
Sadly Mr No Repeal Eisenhower, who could have saved us from the looming ruin we now face, didn’t but rubber stamped FDR’s high handed lawlessness instead.
