The amendment process is slow and complex by design. It's not just a one-off supermajority, but rather a supermajority in both houses of Congress (or a special amending convention) followed by a supermajority of states each individually ratifying a proposed amendment. The most recent constitutional amendment took over 200 years to be ratified.
The nature of the process makes it very difficult to misuse constitutional amendments a mechanism for implementing policy to deal with ephemeral controversies or emotion-laden causes. The only time that really happened was with the 18th amendment, and that was a disaster, which ultimately was repealed.
