Losing to much money n resources when raided

[Naptownmark]

I'm attempting to get 12,000,000 dollars to upgrade fugues but when I use gold tht I've paid for to buy shield I should also be allowed to attack anything n everyone on my map without losing shield. If the shield expires Im open for attackes n when u have 9,000,000 cash everyone wants to attack n u lose alot more, a whole lot more than u gain n revenge attack making it harder to reach my goal unless I buy another shield attacking resources tht only reward u with Penny's n lowball rewards.
