Saudi Arabia may have finally cracked its reputation among the American elite, at least in part. While wealthy Silicon Valley liberals and the D.C. foreign policy "blob" don't particularly care when that country casually blows up a school bus full of children, it turns out they care quite a lot when it allegedly assassinates a Washington Post columnist — that is, someone rather like themselves. Thus elite journalists and Big Tech tycoons are dropping out of the so-called "Davos in the Desert" investment conference in Saudi Arabia.

However, there is one large exception: the financial elite. So far most of the big bankers are staying in. BlackRock's Larry Fink and Blackstone's Steve Schwartzman are still going to speak there, as well as Treasury Secretary Steven Mnuchin.

This is shameful. It's also a good occasion to recall one quick and easy way to take the American plutocracy down a peg or three: by enforcing existing tax law. It's highly, highly likely that many of the financial vampires heading to Saudi Arabia aren't paying what they owe. Staffing up the IRS with aggressive analysts and auditors and siccing them specifically on the top 1 percent is likely to cut income inequality substantially and rake in a tidy sum for Uncle Sam.

A good indicator of the level of tax-dodging in this county can be found in the gargantuan New York Times story about how Trump built his initial wealth. It's a spectacular piece of reporting, worth reading carefully and in full. But in essence, Trump reportedly received at least $413 million from his father through a huge number of questionably-legal acts and several "instances of outright fraud," as the Times writes.

This story got little attention, because fresh Trump scandals (and other disasters) are constantly flushing the old scandals off the front page, providing a sort of protective effect. Whether it's his constant flagrant violation of the Emoluments Clause, his alleged hush money payments for adulterous affairs, his grotesque failure to rebuild Puerto Rico, his staggeringly corrupt Cabinet, or any of a dozen others stories, another scandal has reliably come along to distract the public from the last one.

So it's worth taking a step back to really internalize the Trump tax scandal, because it goes to the heart of how American government has been gradually undermined by corruption. Starting in the mid-20th century, the president's father, Fred Trump, built up a gigantic real estate empire, and being such a skinflint, spent almost none of the proceeds on himself. Instead, from nearly the moment they were born, Fred reportedly transferred huge sums of money to his children, by fair means and foul. He established trusts for his children and hired them directly in some instances. Some taxes were reportedly just straight-up not paid at all. In one particularly egregious case outlined by the Times, he reportedly set up his kids with a fake independent contractor service, which did nothing but pad existing service prices by 20-50 percent.

But probably the key tactic was real estate appraisals that reportedly drastically undervalued Fred's properties. When he was near death, the Trumps reportedly got bunk value estimates that meant they only had to pay gift or estate taxes on a fraction of the properties' worth. Ownership transferred, the children could reportedly then sell the properties at their real value and rake in massive free profits. Overall, the Times reporters estimate that the Trump parents transferred well over $1 billion to their children, which by rights should have incurred a roughly $550 million estate tax bill. Instead, they reportedly paid $52.2 million.

The remarkable thing about this was that the IRS reportedly cottoned onto many of the various alleged scams and forced the Trumps to pay up — but only a tiny fraction of the actual amount owed. In the case of a $17.1 million property claimed at just $2.9 million, an IRS auditor reportedly made them increase the value by ... $100,000. Even back when America was dramatically less corrupt than it is today, entitled rich jerks were constantly skating on egregious tax scams.

Donald Trump made his own attempts at real estate investing, but he was lousy at it and went bankrupt repeatedly. But he was a savant at getting media attention and used his inherited riches to carefully cultivate an image as a self-made businessman. From then he became a national celebrity, a reality TV star, and then president of the United States.

Can there be any doubt that if a couple of battalions of tax inspectors took a very hard look into the books of the American plutocracy, they would find a veritable tax avoidance rat king? A Bloomberg report several years ago detailed the blizzard of legal loopholes Sheldon Adelson was reportedly using to protect his gargantuan fortune from taxes. But what people sometimes forget is that using legal trickery to avoid tax is itself illegal. And with the IRS increasingly gutted, plutocrats are getting increasingly lazy. Just look at Paul Manafort's hamfisted tax fraud schemes! I would wager quite a lot that a dedicated IRS audit could find more than a few nickels for the U.S. Treasury in the Adelson couch cushions.

Republicans have steadily strangled the budget and workforce of the IRS, more-or-less explicitly because that powerfully enables right-wing politics. The more tax that wealthy donors can dodge, the more that is available for campaign contributions and wingnut welfare "think tanks." But the converse of that reality is that simply forcing the rich to pay taxes is a powerful engine of egalitarian politics. (Given all the recent Republican tax cuts, today that would require increasing statutory tax rates as well.) It's a safe bet that would also take a sizable bite out of the Saudi lobbying industry, as laundering foreign bribes is one of the most common tax crimes committed nowadays (witness, again, Paul Manafort).

Ultimately, if Donald Trump had been forced to follow the letter of the tax law back in the 1980s and '90s, it's highly likely he would not have been able to boost himself into the media stratosphere and would not be president today.
