I don't represent any view point on the law just telling you how it is. There's always multiple competing priorities. Ultimately not a politician so it doesn't really matter what I think.
If we're talking morality I don't see how it's moral to ask the law to protect you from being found out doing the wrong thing. If these people don't pay their fair share the rest of us have to pay more.
What if a law change prevents the government from enforcing environmental legislation from illegal land clearing or dumping? What if a farmer illegally diverts more water than they are allowed to from a river or with a well? It's not just about you and me but the whole country.
On robodebt:
that has nothing to do with privacy, tax records aren't private from the government? That's just bad tax enforcement.
