If they have money, then a legitimate way of living here is open to them. A pension, old enough for marriage or retirement extension! Younger but have rental income or wealthy, try an Elite Visa or get married. It isn't about Thai government officials legitimately owning a particular brand of car.
What is important to you is not what governs Thailand's efforts, you, like me, are simply a guest, not some superior foreign advisor!
I would welcome some longer term alternative to my annual renewal, I fear for those getting too infirmed to achieve this, but it is far from difficult.
Pointing at other issues is distraction....
