Men are much kinder to one another

A friend of mine is scheduled to attend one of those Tupperware-type parties next week, where someone tries to sell the attendees a kitchen gadget, a styling cream or knitting accouterments.

My question: Why is this strictly a female phenomenon?

Why aren't there parties for men, where tools, golfing gadgets, ties, or other male accessories are sold?

Perhaps more accurately, what would possess a woman to want to gather her friends in her home and subject them to a three hour sales pitch? It sounds dreadful to me, but ladies do this all the time, and most of their friends seem to respond positively to the invite.

And those that don't often attend anyway, out of a misplaced sense of obligation.  If your friend opens a beauty care shop, I'd expect you to eventually stop by.  But your friend wants to bring that goop into your living room on a Thursday night under the pretense of a party?

It's okay to say no. 

But like I said, most women seem to genuinely enjoy these events, or they're doing a hell of a job faking it.  

Does shopping possess so much of an allure that it must be brought to the living room?

I asked this question to a friend recently and she thought that I had hit on a great business idea:

Sales and marketing parties for men.

"Yes," she said (into my voice recorder). "That's a great idea. Tools and ties and stuff like that would be perfect. You might have found a real moneymaker."

Sadly, I had to explain to my friend that hell would likely freeze over before any male friend of mine would attend a party like this.
