How does a political party dedicated to the material interests of the top 0.1 per cent of the income distribution win and hold power in a universal suffrage democracy? That is the challenge confronting the Republican party. The answer it has found is “pluto-populism”. This is a politically successful, but dangerous, strategy. It has brought Donald Trump to the presidency. His failure might bring someone more dangerous, more determined, to power. This matters to the US and, given its power, to the wider world.

The tax bills going through Congress demonstrate the party’s primary objectives. According to the Center on Budget and Policy Priorities, in the House version of the bill, about 45 per cent of the tax reductions in 2027 would go to households with incomes above $500,000 (fewer than 1 per cent of filers) and 38 per cent to households with incomes over $1m (about 0.3 per cent of filers). In the more cautious Senate version, households with incomes below $75,000 would be worse off. This simply is reform for plutocrats. (See charts.)

That is far from all. The bill might also increase the cumulative fiscal deficit by about $1.5tn over the coming decade. Yet, according to the independent and respected Congressional Budget Office, the US fiscal position is already on a deteriorating path, with spending forecast to rise from 21 per cent of gross domestic product in 2017 to 25 per cent in 2028-37. The planned tax cuts would worsen the pressure to cut spending. The outcome desired by the Republicans is to slash spending on nearly all of the non-defence discretionary spending of the federal government, plus its spending on health and social security.
