Or, the tariff makes the price of imported product too high to buy (the main aim in most cases), so then there are no imported goods to tariff so no income. The farmers get their high price but the poor locals are paying more than necessary for their rice.
By all means support the farmers with time limited loans and grants to help them adapt/improve/transition but don't budget it from tariff income as there likely won't be any.
The US government is making piles of cash from the China trade war tariffs right now. But where is that cash coming from? Not from the Chinese vendors that's for sure, their price is the same on arrival at the US. The cash is coming out of the pockets of importing Americans paying the tariffs, or paying higher local prices instead. Then the US government has to pay subsidies to support those suffering from the retaliation tariffs. Crazy.
If agriculture output could be doubled (easily achieved) poverty levels would collapse overnight.
You ask what the problems are that have held the Philippines back? Well I could write a book on that - but in a nutshell "The Families". The landowning feudal aristocracy from the Spanish era (and that includes the Catholic Church). They own the media (newspapers and TV), Congress, the land, much of business legal and illegal. They have private armies to enforce their empires. The Philippines never had the revolutions that happened in Europe so the aristocracy are still in charge.
The end result is corruption and complete blocks to competition including a Constitution that legally prevents it. Why would you want competition when the status quo is so profitable? A totally ineffective judicial system. A corrupt media.
Duterte is a junior baron in English historical terms but is trying to smash it up - hence the language as he has admitted himself. However the aristocrats are exceptionally well connected, for example the Clintons, hence the disconnect between the views of Filipinos and the outside world. If Duterte fails then I think there will be an uprising with the end result a Marcos back in power perhaps followed by the communists.
It's a bit silly to say you can move to a free market overnight since it doesn't really exist anywhere. Every country has policies to protect certain industries. It's all very easy to say that it's good for "the people" but everywhere there are different vested interests with links to power. It's simply unrealistic to say that a government can act in a vacuum. Those who are in power whether in a democracy or not have debts to pay and are accountable to others. A totally free market is about as achievable as peace on earth.
Another SCMP classic "Duterte channels Marcos in calling for Philippines name change". Though to be fair the article is taken from Bloomberg.
Unless you consider "perhaps someday we should change the name" to be calling for the name change.
The name of Maharlika was first proposed by a Liberal Party senator in the 1960s and then taken up by Marcos.
It is not a particularly novel idea: Ceylon to Sri Lanka, Rhodesia to Zimbabwe, wasn't Taiwan called Formosa?
It would be a good idea to change the name of the country to better reflect its inhabitants instead of honoring the colonial oppressors of the past
History (I might have got some of the years a bit out)
2010/11 Supreme Court orders land in the Aquino/Cojuanco Hacienda be distributed to tenant farmers under the land reform Act
2011/2012 Aquino refuses to give up land, farmers strike, some are shot dead
Chief Justice of SC Corona says he will seek justice for the farmers
Rappler is founded receives a lot of money from the Liberal Party and associates
Corona faces impeachment (purely coincidentally)
Rappler launches a long series of attacks on Corona and his associates which is where this libel comes from.
