Okay, so, realistically, if the guy in the article wants a woman to be in the dark as to what his net worth is, he'd need to:

1. Use a fake name.

2. Create a fake story as to what he's been up to for the last five years professionally.

3. Get an ordinary apartment, car, clothes, etc. all for the purpose of appearing to have regular income.

4. Get his friends to support his fake name, fake life, fake career story, etc.

5. Get his family to support his fake name, fake life, fake career story, etc.

You don't think all that counts as lying?
