Sometimes the fact that more people have something is not a bad thing. Even if 1% of your country wore the same model of the nicest Nike/(insert any popular company) shoes they would still be the nicest and you would still be in a minority of those who wear stylish shoes.
Then you could spend a lot of money for shoes that look like this:
And most probably you wouldn't look better. Chances are most people would consider them ridiculous.
Maybe except of people who designed them and those who have no style and a lot of money to buy them.
Same with cars - you can buy an expensive car that looks more gay than a cheaper one.
I'd say it's just easier to buy something better while spending more money but it's not a rule.
I see people who dress terribly while wearing expensive clothes daily.
You can't buy style and the most terrible thing you could do would be thinking that you have style because you are wearing expensive clothes that not even necessarily match.
