A country goes broke when it defaults on its national debt. The US is nowhere near that point. You might have wondered who the national debt is owed to. It's owed to anyone with money who buys government bonds. Governments borrow money by selling bonds, and paying interest on those bonds. Bonds are usually a safe option, as countries don't often go bust, although I noticed the US's credit rating was downgraded from AAA to AA+. Germany, Denmark, and other countries are still AAA. The UK is AA. Not sure how meaningful ratings actually are, as the financial products that crashed the economy in 2008 were given an AAA rating, due to corruption at the ratings agencies. I.e. "give us an AAA, or we'll take our business elsewhere". Ain't the free market great?
The US national debt is 32.6 trillion dollars. It sounds like a lot, and it is a lot, but the US is a big country with a big economy, and it makes more sense to give the national debt as a percentage of GDP.
The national debt has been over 100% of GDP before, at the end of the Second World War. Bad stuff happens, and the government borrows money to get the economy out of a hole. That's Keynesian economics. There is a precedent for reducing the national debt, as seen in the period from the 50s to the 70s. To reduce the national debt, the government has to run a budget surplus, i.e. take in more tax than it spends. The US isn't broke if it has a GDP of 26 trillion dollars in 2023. It needs to balance its books.
You can have a go yourself :
In 2019 the cost of the national debt was 327 billion. The problem is the deficit, which is the difference between the amount of tax collected and government spending. What would you do?
To me, the obvious solutions are to cut defence spending or collect more tax. Now, I'm not suggesting you pay more tax. Get the tax from the rich, who can afford it. Taxes can either be progressive or regressive. With a progressive tax, the more a person earns, the more a person pays. Regressive taxes disproportionately hit the less well off. Like in the UK VAT (value added tax) is a flat rate -- it doesn't take into account how much a person earns. This is a regressive tax, as the poor pay more as a percentage of their income. The UK tax system is pretty regressive. There is duty on booze, cigarettes, and petrol which are regressive taxes.
Progressive taxes, then, are how to raise more tax without making the poor poorer. But then the rich whine. The snowflake rich don't want to make an appropriate contribution, and it becomes a political problem.
Where are you getting " the US is broke"? It sounds like something the right wing would say to justify cutting government spending. And that wouldn't be defence spending, again for political reasons.
