It isn't laziness.

Change is disruptive. Disruption during instability (such as the economic condition of our country, political instability due to polarized nearly 50/50 political split of the people) is dangerous. But more importantly, estabilished lobbying powers inherently tend to equalize change unless one or more become significantly stronger and change the balance of power. And if those lobbying powers are not in favor of the change, it won't happen. Finally, change can lead to a great deal of uncertainty. Uncertainty is risk, and risk is typically bad when it comes to politics.

Amendments to the constitution could happen of course, but this would be an unlikely time for them.

It is more likely that the interpretation of the constitution would change. And that has changed very much over time.

It's not laziness, it's willful ignorance. Much worse.
