空　２: 日本の国民は世界的にみると経済的に全然豊かじゃない。

大抵の国に該当する事実：医療へのアクセス、身の危険を感じずに出歩ける、水道水が飲める（これはOKな国は多少は絞られる）…を日本特有のものと信じてる面々が「井戸の中で日本凄いと言ってる」の証左となってる

日本は「豊か」なのか？https://t.co/Ec2Xjjrq0b

円建て名目GDPと為替の相関係数が1だった場合、「ドル建てではゼロ成長」ということにならないか。
元twに「円安が経済成長をBoostする」というニュアンスを感じるのだが。 https://t.co/jMqFk8fcQv

2014年に地下経済のカウントを開始した際のUKの名目GDPへのインパクトは+0.7%
日英の地下経済の規模は同じぐらいなので、日本で同じことやっても+0.7%程度でしょうね。https://t.co/vncNJzuD55 https://t.co/MRonm5aeYM

日本復活の為に、外国人を大量に入れよ❗️
①経済成長は人口増から
③外資に食われた方が発展する❗️

豪州やカナダの経済をみると、移民を入れてGDPはそこそこもっているのだが、一人あたりのGDPは減少

外資については法人税を安くてして驚異的にGDPや一人あたりのGDPを伸ばしたアイルランドが参考になる。

Why Ireland’s Economy isn’t as Rich as you think

- **Ireland’s Apparent Wealth vs. Reality**: Despite a high GDP per capita reported by the IMF, actual average incomes in Ireland are significantly lower, at about €1,000 annually. This discrepancy highlights a contrast between impressive economic statistics and the lived experiences of many Irish citizens.

- **Impact of Multinational Corporations**: Ireland's GDP figures are inflated by significant foreign investment from multinational corporations benefiting from low tax rates and favorable policies. However, the actual economic benefits for local residents are minimal, as profits are often repatriated abroad.

- **Housing Crisis**: The influx of multinational companies and a deregulated housing market have led to a severe housing crisis in Ireland. Rising property prices and limited rental availability have resulted in widespread unaffordability and a high level of homelessness.

- **Misleading Economic Indicators**: Traditional GDP measurements exaggerate Ireland’s economic prosperity. Alternative metrics like Gross National Income (GNI) and GNI* offer a clearer picture, showing Ireland’s economic standing is lower than suggested by GDP alone.

- **Economic Improvement Over Time**: While Ireland is not as wealthy as headline figures suggest, the country has made substantial economic progress over the past 30 years. Although it’s not the richest nation globally, it has seen significant improvements compared to its past economic state.

　多国間企業を読んでGDPは上がり、以前より経済はよくなったものの地元住民はGDPの驚異的伸びたわりには恩恵を被っていない。

　外資企業の投資や輸出は伸びてGDPは伸長したが、その利益は地元には還元されていない。

"Leprechaun economics" is a term coined by economist Paul Krugman to describe the significant distortion in Ireland's GDP figures due to the activities of multinational corporations. This phenomenon became particularly notable in 2015 when Ireland's GDP appeared to grow by over 26%, later revised to 34.4%, largely due to tax strategies employed by these corporations¹².

Here's a breakdown of what happened:

1. **Tax Strategies**: Multinational companies, like Apple, used Ireland's favorable tax laws to shift profits and intangible assets (like patents) to the country. This artificially inflated Ireland's GDP without corresponding real economic activity¹².
2. **GDP vs. GNI**: While GDP measures the total economic output within a country, Gross National Income (GNI) accounts for the income earned by residents and businesses, including those abroad. In Ireland's case, GNI is significantly lower than GDP, highlighting the disparity caused by these tax strategies².
3. **Modified GNI (GNI*)**: To address these distortions, Ireland introduced a modified measure called GNI*, which aims to provide a more accurate picture of the economy by excluding the effects of these multinational activities¹.

This situation has led to debates about the true state of Ireland's economy and the impact of tax policies on economic data².
