The problem is not with the 10th amendment or most other amendments, some of them are the best part. Of course if it takes so many amendments to cobble the original document into something that can be lived with, it could well be best to toss the whole thing as their are several existing ones out there that are far superior to replace it with.
The problem is the way biased Supreme Courts have interpreted and ruled on it.
The Constitution does give lifetime appointments to Supreme Court Justices, (a big mistake), but what it does NOT do is give the Supreme Court the right to interpret the Constitution. The Supreme Court gave that to itself. And has done it in some incredibly horrible ways, which become precedent, and re-interpreted, and so on and so on, allowing things like people with enough $ being able to avoid justice.
The fact that the Constitution CAN be amended (just look at the ERA, it may take a long time and suffer the efforts of "those who should be burned in effigy on an annual basis" but it shows that ammendments CAN and WILL be done. And SHOULD be done. On a regular basis.
The whole "isn't it great we can amend the Constitution and isn't it too bad it can't be done" is just another smoke screen, the tyrannical minority spending money on propaganda to convince us it is futile to try and make anything fair or sensible. The fact is the majority of US citizens agree on sensible things, like people should have control of their own bodies, each person should get one vote*, we should not have to live in fear of maniacs with military grade weapons, the police should have to obey the law, no one should be above the law, and on and on... any of these things could make it easily if dark money can be kept out of it, but that's another matter entirely.
*if anything, the 2016 election proved once and for all that the Electoral College does not work as intended. According to Hamilton, one of it's primary purposes is to prevent a populist demagogue from ever becoming President. That sure didn't work!
