The business and political establishment is still running the place.

It wouldn't surprise me if he was more interested in proving he knew the right buttons to press to be president, or was popular enough to be president - that he could ensure he was the last contestant voted off the island - than he was actually doing a list of things to "make America great again". How keen will he be to take on four years of 18-hour days making unending judgment calls? When you think of all the struggle needed to "drain the swamp", he strikes me as more Phony Tough than Crazy Brave.

Most of columnist Aubrey Perry's family voted for Donald Trump. Much of the commentary we've seen so far is very "great man theory of history". Trump is such a wild man, he'll single-handedly destroy the American alliance, end America's world supremacy, start a global trade war that reverses globalisation and resumes the Great Depression, and maybe provoke a shooting war with China. Was that in his first term, or would it take two? Trump isn't part of the standard two-party system and didn't win the election the orthodox way.

They say that in the race of life, you should always back Self-interest because at least you know it's trying. I'd also put a couple of bob on Inertia. In the coming history of the Trump administration, I see big roles for self-interest and inertia, aka the status quo. Start with the Republicans. The hated usurper Trump, rather than dumping them in it, has had a famous victory in their name, ensured Republican majorities in both houses of Congress, and acquired control over countless perks and preferments. If you were in the Republican caravan, what would you be doing? Sucking up. There's an army of worthies - academics, think-tankers, bureaucrats, retired generals, former lobbyists, business people and Wall Street bankers - who spend their careers moving in and out of taxpayer-funded jobs in Republican administrations.

Trump will be knocked over in the rush to be his special friend. The thousands seeking a gig will have two dominant motivations: a share of the spoils of office and a say in the shaping of policy. There's probably only one Republican in the country who agrees with every item on Trump's supposed to-do list, and that's the man himself. If so, every other Republican will be hoping to persuade Trump to drop this, tone down that, add this and put that one on the backburner. Do you really think he's going to spend his 18-hour days ensuring every bright sales idea written on the back of an envelope during the campaign remains inviolate? What about all the real, professional econocrats, diplomats and generals? "Alienate our closest allies? Start a trade war? Good idea, Mr President."

Remember, too, that presidents often have trouble getting their policies passed by Congress, even when it's of the same political colour. There's far less party discipline in the American political system, with individual congress people requiring a small bribe (hopefully, only something for their constituency) before they toe the party line. They're also anxious to keep sweet with the main interest groups that contributed to their campaign costs. Which brings us to Washington's other big industry, the lobbyists. They're going to meekly bow before Trump's sacred list of bright ideas, are they? No, they're going to go on doing what they're so handsomely paid to do: mould the actions of president and Congress to fit the perceived interests of their generous customers.

Who are these big-spending interest groups? Well, the ones with the most money to splash around are the ones representing the most successful and powerful industries. The gun industry, for instance. But, right at the head of the list, Wall Street - the people whose greed caused the global financial crisis, who got bailed out by the taxpayer, avoided going to jail and left millions of ordinary people to pick up the pieces of their lives. Many of those ordinary people are those who voted for the larrikin Trump, hoping he'd give Wall Street an almighty kick up the bracket - he being a regular plain-talkin' guy, just like them. Get it? The business and political establishment is still running the place, still ensuring their interests are put ahead of those of the lesser mortals silly enough to vote for Trump. Now Trump has no choice but to turn to them, seeking their help in running the joint and implementing his brave plan to put them and their paymasters back in their box.
