I don't know, I think some politicians get along and have similar ideas like others more than people know or give them credit for getting along or being alike.
The wealthy of our country and other countries is who controls them. At least most of them. Why do you think we even have these policies? Because people in Washington DC are accepting lots of outside money. So ask yourself why Obama was the same? Obama went to Harvard University the same as the Bush’s. So ask yourself why they had pretty much the same policies?
Your answer is there.
Obama was paid off to do the Bush family bidding.
