In advanced economies the average salary should be 10 to 15 % higher than GDP per capita with a GINI around 0.26 richness indicator level ( «0» indicator means highest distribution of richness , while «1» means poorest distribution of richness ) .
As GDP per capita overcomes average salary and GINI indicator mounts over 0.30 , middle class will require an excessive and permanent rate of credit ( indebtment ) to keep balance between offer and demand and as debt grows beyond levels sustainable by financing institutions , drastic rupture of balance between offer and demand will occur and economy will enter an era of recession and/ or depression depending on the measures taken by respective authorities .
As the economy considered is specially rich with GPD per capita above 50.000 $ , the GINI indicator may be relaxed up to 0.32 level .

I have been surfing online more than three hours today, yet I by no means discovered
any interesting article like yours. It’s pretty price sufficient for
me. In my view,
if all site owners and bloggers made excellent content as you probably did, the internet might
be much
more helpful than ever before.
