The US could maintain current welfare state dysfunction and simply add a 3-4% value-added tax, which would solve the fiscal problem without requiring austerity or drastic measures.

In America, for people earning zero to $60,000, taking an additional job and earning extra income causes them to lose a dollar of government benefits for each dollar earned, creating a 100% marginal tax rate on labor supply.

During the 1990s, US economists were writing papers about what the country would do when it had paid off all government debt, reflecting the success of 1980s reforms in creating fiscal sustainability.

Europe in the 1980s experienced an economic revival through regulatory reform and structural reforms, with countries like Sweden abandoning socialism during this period.

If governments bail out banks during crises, bank-created money effectively becomes government money, because it then represents a claim on government surpluses, making it inflationary.

New Keynesian economists have focused on inside money (bank credit) as the transmission mechanism for monetary policy, but this omits government money's role in determining the price level.

The euro faces deeper debt sustainability problems than the US because it has one ECB and multiple governments that spend money; it remains unresolved whether the ECB will print money to bail out governments or allow bondholders to take losses.

Cochrane co-authored a book on the euro titled 'Crisis Cycle' with Luis Garicano and Klaus Masuch that analyzes eurozone sustainability problems in detail.

Fiscal reforms that appear politically difficult now could and should be implemented before the next crisis rather than in emergency conditions during crisis.

Economic growth is the most important tool for paying off national debt, especially for Europe, and achieving growth requires looking at incentives and removing regulatory barriers.

Modern central bankers have given up on the Phillips curve as a causal mechanism for controlling inflation and instead focus on expected inflation; they believe that by giving speeches about future low inflation, they can anchor expectations and prevent inflation without raising rates.

The 1980s US tax reform lowered the top marginal income tax rate from 70% to 28% while cutting loopholes so extensively that the reform actually increased total tax revenue.

Private banks create money (inside money), but inside money is not inherently inflationary because when a bank makes a loan, the borrower gains an asset and a liability, with no net wealth creation.

Governments throw money down rat holes through inefficient spending; the Italian government provided 110% reimbursement for energy retrofitting, creating perverse incentives for citizens to gold-plate projects and submit inflated bills.

Western governments are starting to hit the limits of what people believe they will be able to repay, not necessarily the limits of total debt that could theoretically be borrowed if confidence in repayment existed.

The real problem underlying government debt crises is not the debt itself but unfunded entitlements and spending plans driven by aging populations that don't add up mathematically.

Expectations are anchored by fundamental faith in institutions—both central banks and fiscal authorities—to solve problems when needed; the key question is not whether expectations are anchored but what anchors them.

Europe has suffered economically since 2010 from combined high taxes (marginal rates 70-80% including corporate tax, income tax, and VAT) and regulatory burden that have stifled growth, while America has grown 40% better than most of Europe.

Germany has fairly sober fiscal plans but has undermined its ability to pay back debt by achieving poor economic growth, since government tax revenue is determined by the tax rate times the size of the economy.

Birth rate collapse in the last 5 years has been much swifter than economists previously imagined, making demographic forecasts less reliable than they appeared.
