Spend thrifts ......sanfransisco.ians
The recent study ...

The Bay Area’s average annual spending of $56,100 was possible because residents made a before-tax average income of $70,200, according to the data. U.S. average expenditures were $38,800 on pretax income of $46,100.

Infact, San Francisco wasn’t tops in all areas of spending .
while New Yorkers spent the most on clothing ($3,000);
Bostonians the most on tobacco ($369);
Chicagoans the most on housekeeping supplies ($590);
and Washingtonians the most on entertainment ($3,033).

So from this we can understand that being master in one is not enof. we can be jack of all trades and appear to be first on all :)
This is what i learnt as the first lesson in the management school where i am doing my Masters :)
