We are Ferenginar

And the Donald is the grand Nagus.  

Ferenginar is the Star Trek created world that is motivated by profit.  Their leader is the Nagus, who helps guide them to profitability. 

All Ferengi live by a series of "Rules of Acquisition."  On the show, they'd sprinkle them in from time to time, mostly via a character named Quark, who ran a bar and was quite the nefarious one. 

Here are a few of those rules that the Donald may use in his everyday life:

"Once you have their money you never give it back."

"A woman wearing clothes is like a man in the kitchen."

"Always exaggerate your estimates."

"Nothing is more important than your health...except for your money."

"Keep your lies consistent."

"Ask not what you can do for your profits, but what your profits can do for you."

"There are many paths to profit."

"Enough...is never enough."

"Trust is the biggest liability of all."

"When it's good for business, tell the truth."

"Everything is for sale - even friendship."

"There's nothing wrong with charity... as long as it winds up in your pocket."

"Sell the sizzle, not the steak."

"Let others keep their reputation. You keep their money."

"A good lie is easier to believe than the truth."

"A wife is [a] luxury... a smart accountant a neccessity."

"A man is only worth the sum of his possessions."

And of course, the Donald looks suspiciously like the Nagus. Well except maybe the ears. No umax for him!
