So here go the Chinese again.  After objecting to their human rights status in the world, they execute a guy who didn't kill anyone.  It seems that for being a swindle and a cheat, you get to die in China.  And he didn't even do anything that bad, in my opinion.  Hell, it was the government's fault, if you look at it right. 

He convinced a bunch of people that he could breed this special ant, crush it up and make various concoctions with it, and sell it as an aphrodisiac.  One of the investors killed himself after giving his money to this guy. 

1) In my world, that's a free choice, and while the guy was a douche, he didn't KILL the investor. 
2) If you're a big enough idiot to think you can turn people into sexual machines by crushing some ants in their tea, you're an idiot.  After all, everyone ALREADY knows about Horny Goat Weed.  Also interesting is that Drugs.com wasn't anywhere near the top of the google page, being beat out by nondefinitive, nonmedical sites about a freaking DRUG. Notable quote of the article there:"Little or no efficacy."
3) The Chinese government encourages it's citizens to use and endorse "natural" or "traditional" medicine, a large part of which are remedies such as aphrodisiacs.  This it does because Western medicine, with all it's fancy sanitation, drugs, surgery, etc. may actually work, but just cost so damned much.  And when you have nearly half the world's population to consider, well, it's just better to have a big bankroll, so go eat some antelope antlers for your cancer, and rub some crushed up dung-beetles on your 5-inch cut to the bone.  And before anyone says, "That's their culture, of course they do it that way,"  I'd like to remind you that government officials, all their olympic athletes, military officials, and anyone else that's IMPORTANT to the government gets WESTERN medicine.  So by perpetuating this crap about natural healing, they encouraged the investors to look past science and think this guy had any legitimate reason to breed ants.  In America, we would have asked the guy to isolated whatever he thought the aphfrodesiac chemical was and run some tests, then figure out how to synthesize it to make a controllable drug.  If he didn't have those plans, he wouldn't have gotten a dime. Period.
