I think there's a lot of ways things could be fixed without necessarily "tearing everything down". More like shifting in a new foundation while leaving a lot of the superstructure intact. Like we could still have a lot of the same basic governmental functions and operations even if the constitution were entirely rewritten.

The irony is that Trump is doing the exact opposite, tearing down those "surface-level" operations without doing anything to improve the foundations ---and in fact causing major cracks in those foundations, thus making it even more necessary to replace them.
