but in this mass is a little part what will buy anyway.

it always depends. i know a lot of tube webmasters what are making 50-100 thousand per month - and more.
and finally it is what you have left at the end to spend.

someone who makes 100 k per month will always have more left in is pocket as someone who makes 5 k.
