I've recently been thinking that the middle east is ripe for PE investments. I worked at one of the largest banks in Saudi last summer and I remember that the Blackstone guys from London came down to ask us about investment opportunities. I know that KKR is setting up shop in Saudi as well and have already done so in Dubai.
There are just so many private companies that have a lot of potential but are not run that well that it seems like an amazing place to operate out of. That is, if you are like me and actually enjoy the Middle east / the culture, or at least don't mind it enough to let it get to you.
When you put the fact that you can work half the time, live in a penthouse, eat amazing food every day, save 90% of your salary, and have 50 days vacation time a year to enjoy it all it seems like an amazing place to operate out of.
I'm just a freshman, so take what I say with a grain of salt, but I think that this may be the next big thing.
