This is from Michael Roberts (a marxist economist) blog. He notes that the actual problem being experienced by the G20 is low profitability, which is why proposed solutions like "make people save more so they can repay debt, hope that it doesn't lead to a depression as they spend less" and "keep growing the economy by slashing regulations and cutting taxes, even though debt hampers economic growth" can't work anymore.

One potential solution floated by capitalist economists was to issue special drawing rights (an IMF thing that's kinda like an international gold-standard money for settling debts) and let countries float a little longer on that as a form of credit - but the US vetoed doing that for this crisis already.

Which means, this (meaning the covid depression) could very well be the untractable contradiction of neoliberalism and we're reaching the end of it right here and now. What comes next is either Great Reset cyberpunk neo-feudalism or socialism over the next couple decades.
