I own my home... so that would increase the 1% compare to people that only rent. What about people with mortgage? Should I pay for my full home or only a half because my wife owns the other half?

How would be possible to avoid frauds?

Exactly. You own more than people who rent. But still if only half is yours that would be fair to consider.

Maybe AI would be solution. Feed it all bank statements, private records, emails, tax records and so on from say past 10 years. Then it can come up with correct figure...
