I don't think all men have it easier, but I think a certain type of man does. I call them salesmen, because a lot of them gravitate in that direction for reasons that will become clear shortly.
The salesman is over confident. He has to be, he knows he's going to get knocked back a lot but this doesn't bother him, because he's casting his net wide.
The salesman also lies. He says what he needs to do make the deal. It doesn't matter if 6 months down the line the product (himself and the relationship) turns out not to be what you thought you were getting. He's already working on the next deal.
The salesman is successful, or at least looks it. He has the nice car, (that work probably paid for), he dresses well, he pays for dinner. Until you look behind the curtain and find out that he's drowning in debt.
The salesman is not monogamous. He is always working a lot of angles, it's not the end of the world if he doesn't land this deal, there's another 3 in the pipeline.
Now before I get a lot of grief from people who work in sales, I'll just offer the disclaimer that not all salesmen are "salesmen", but a lot of "salesmen" tend to work in sales.
And as an example I will give you Delboy. Derek Trotter never had a problem getting a date. At first glance he was a successful business man, he wasn't good looking but had the confidence of a good looking man. He genuinely cared about his family, but even Raquel and Rodney couldn't trust him. He seemed like a decent bloke until he isn't, and the next deal coming down the pipe probably also thinks he's a decent bloke.
