I'd say the go-to place would be my bank statement ;)
More seriously, I don't particularly care what strangers do with their €/£/$/whatever. As an aside, I don't get the general mockery of consumer spending. That "stupid" spending is what drives the economy, and without it, your dividends, net worth growth, and retirement plans are going to dry up. Is it wise for people to buy 5€ coffees and expensive cars with expensive credit? No. If they all suddenly stop, will it hurt your portfolio? Quite probably.
Don't sweat what other people think of you, don't read the news, eat well, exercise well, stay healthy, stay lucky.
(yes, I realise I sound like a goddamn hippy, the worst thing is that I don't even care any more ;) )
