MMT will collapse the economy and the dollar.

Most governments will try to cover their fiscal and trade imbalances by devaluing and making all savers poorer.

“A country with monetary sovereignty can issue all the currency it needs” is also a fallacy.

Monetary sovereignty is not something the government decides. Confidence and use of fiat currency are not dictated by the government nor does it give said government the power to do what it wants with monetary policies. Citizens all over the world have stopped accepting the government-issued and denominated currency when confidence in its purchasing power has been destroyed after increasing the money supply well above its real demand.

That is why the Sucre in Ecuador or the Colon in El Salvador collapsed or why the Argentine peso and the Venezuela bolivar or the Iran Rial are widely rejected by local and international citizens. There are numerous fiat currencies that have failed or disappeared. As Michael Sanibel writes, “a nation’s currency is not exempt from the laws of supply and demand, so the more that is printed, the less it is worth“. Currency collapses and failures are frequent, but, more importantly, even if some survive, its domestic and international demand is irreparably damaged.

Given that the world of currencies is a relative one, the average citizen of the world will prefer gold, cryptocurrencies, US dollars or Euros and Yen despite their own imbalances rather than their own currencies.

Why is this? When governments and central banks worldwide try to implement the same mistaken monetary policy of the US and Europe or Japan but without their investment security, institutions and capital freedom, then they fall into their own trap. They weaken their own citizens’ trust in the purchasing power of the currency.

The MMT answer would be that all that is needed then is stable and trustworthy institutions. Well, it does not work either. The first crack in that trust is precisely currency manipulation to finance bloated government spending. The average citizen may not understand monetary debasement but certainly understands that their currency is not a valid reserve of value or payment system. Because the value of the currency is not dictated by the government, but by the latest purchase agreements made with such means of payment.

Governments always see economic cycles as a problem of lack of demand that they need to “stimulate”. They see debt and asset bubbles as small “collateral damages” worth assuming in the quest for inflation. And crises become more frequent while debt soars and recoveries weaker.
