No money is a tool not a key.

If u come to my door and say "Hey Jennifer, open up, I have a million dollars" I'd probably ask you to pass the money under the door and walk away ... =p ... juuuuust kidding... The most important doors (walls) you have to open (break) are inside of you, so my answer is no, money doesn't open all doors.

I don't know if you can open all the doors with money (i guess it will be some difficult) but what you can do is to buy all the doors you want

so we may say that money may open MOST doors, but not ALL of them )

no, not all, you can't buy the feelings or love with money
