NEW YORK (TheStreet) -- TheStreet's Jim Cramer says he is astonished that David Marcus is leaving PayPal for Facebook (FB - Get Report) because PayPal is the reason investors want to own eBay (EBAY) and Marcus has always been known behind the scenes as the reason PayPal is worth as much as it is.
Cramer says this will become a situation similar to Beats Electronics once Marcus leaves, with the exception of the $3 billion price tag for Dr. Dre and Jimmy Iovine. Facebook gets Marcus, "Mr. Monetization," who finds a way to make people pay without them feeling badly about it.
This, Cramer says, is exactly what Facebook's main issue has been: find a way to make people pay without compromising the user experience. He calls this a brilliant move by Facebook but thinks it is very bad for eBay. He also cautions investors about the daily midday sellers of Facebook.
