Though, as Mr Cat's commenter, Tim Eisele, points out, it's not that the 10th Amendment is inadequate or ambiguously worded, it's that the bureaucrats and politicians -- anf the People -- don't want to abide by the Constitution, including the 10th.
Here is my contribution to K T Cat's thread --
I think that one of the biggest reasons, and perhaps the biggest reason, that the current (and collapsing) behemoth is an anti-liberty behomoth is that people -- even senators and supreme Court (*) justices -- simply don't understand the Constiution, and mostly never try to rectify the lack. It's sort of like the case of the Bible ... everyone has one, and no one reads it.
The nearly universal misunderstanding of the Constitution starts in civics class, wherein we are taught falsehoods about the Constitution which a simple reading of it ought to dispell.
For instance, one of the first things drummed into us in civics class is that we have a federal government of three "co-equal" branches. Now, this claim is false in two ways: it's false by the Constitution (that is, it is fase de jure), and it is false by how the federal government actually operates (that is, it is fase de facto).
De facto, our rulers are various judges within federal courts. And just below the judges are the "permanent government" within the bureaucracy, which is ostensibly answerable to the chief executive.
De jure, the Constitution established the *Congress* as the supreme branch of government.
Another civics class myth is that the Constitution establishes an "independent" judiciary (which is "co-equal" with the other branches). It does nothing of the sort: the Constitution makes the federal courts, and specifically the supreme Court, creatures of the Congress -- the Constitution gives the Congress the authority to declare that almost every matter of law is outside the jurisdiction of the supreme Court (and thus all federal courts): so, for instance, if Congress were so minded, it could simply enact bills overturning both Roe and Obergefell and include provisions declaring these matters to be outside the jurisdiction of the federal courts.
Another civics class myth is that the Constitution grants the power of "judicial review" to the supreme Court, and thus to the federal courts under it. The Constitution does nothing of the sort; the Court's exercise of "judicial review" is an unConstitutional usurpation going back to 1803 -- John Marshall's power grab appealed to the then-current partisan needs of both the Federalists and the Democrats, and so the politicians cooperated [with the judges] in violating the Constitution ... as they have been doing ever since.
Isn't it odd that so many of the myths we are taught in civics class have the effect of making us blind to blatant violations of the Constitution? Really, it's not all that odd -- the tone of our nationalized education was set in the Progressive Era, and the Progressives were all about a stealth overthrow of the Constitution.
(*) interesting tidbit -- the Constitution never mentions any "Supreme Court", but only a "supreme Court"
