And remember that greed is a sin. :)My two cents.

Some people are just greedy, fact of life.

They speak great English because they are born and raised here they know the industry say all the right things.. their main target is the dreamers like Ingrid Robinson was/is.. she was in the health field and decided to do a big development up at Clear Lake CA.. which is where i cut my teeth selling RE back in the 70s and my dad in the 60s .. so when i saw that and the property she wanted to develop there on American greed I was stunned.

Adding all those wealth creators together your overall return is far greater than investing in the market unless you're the world's greatest trader. 

I've built the majority of my wealth as a trader and investor of stocks.

Greed is a blinder & no I would not.

We don't have a corner office in Wall Street like a lot of traders.

A very tiny possibility is that they are just greedy. 

But at the same time don't be too greedy in what you offer.

Investors need not be greedy, greed does nothing but hinder their success.
