Our best tool is to compare Labour’s 2019 manifesto against the Sanders’ economic platform. Doing so makes clear that Bernie is more radical than Corbyn on economics, both in absolute terms and relative to their countries’ respective politics.
Take the size of government. The Manhattan Institute’s Brian Riedl calculates that Sanders’ promises would add $97.5 trillion to spending over a decade, taking total annual US government spending to around 70% of GDP and more than doubling the size of the federal government. Even if climate investments prove a one-off, spending would settle at a massive 64% of GDP. That’s far higher than Labour’s planned 44% and even France’s current 57% (itself the highest in the OECD).
A look at certain individual spending areas also underlines just how radical the Sanders agenda is. Like Labour, he wants government-funded free public higher education. Unlike Labour, he’d also forgive all existing student debts. On climate change and infrastructure, Labour planned for £400 billion investment over 10 years (about 20% of current annual UK GDP). Sanders wants to invest $16.3 trillion over 15 years (about 75% of current annual US GDP.) On healthcare, both want government spending to expand to cover all medical treatment, prescription charges, long-term care for the elderly, and dentistry. But only Sanders would explicitly ban private health insurance (Labour did consider that proposal but held off in the end).
True, Corbyn and McDonnell favoured nationalising buses, railways, the energy sector, water, and parts of the broadband network. Corbyn even wanted free government-funded broadband for all. But even here the results of Sanders’ pledges would bring similar results. He would set up “publicly owned” and “democratically controlled” broadband networks. And his Green New Deal would bring most public transport under government control and deliver effective public ownership of energy production.
When it comes to financing their promises, Sanders is arguably more radical again. Labour planned to only borrow to invest, raising the deficit by about 2% of GDP per year. But Bernie’s tax plans get nowhere near fully funding his agenda. Absent further broad-based tax rises, Riedl calculates annual borrowing would soar to around 30% of US GDP if his spending plans were implemented…
Combined with national insurance, Labour’s top marginal income tax rate would have been 52%. Sanders’ top federal income tax rate alone would be 52%, bringing a top combined top rate of around 80% once state and payroll taxes are considered. Sanders wants a new wealth tax too, another option Labour shirked. And while Labour wanted to raise the UK’s main corporation tax rate to 26%, Bernie would opt for 35% with a broad base.
That is from Ryan Bourne of Cato, and yes there is more at the link.
I would put it this way: right now we are sampling the offer curve of left-wing intellectuals and activists for “prioritizing climate change” vs. “mood affiliation,” and…let us hope for the best!
