While there is corruption in every government, there is also good. Apparently you aren't paying attention to the "good" part and only see the bad. Pity, really.
President Obama has done a great deal for this country and will continue to do so, despite the hurdles he will have to climb.
Have you forgotten about Obamacare? Have you forgotten that the economy is starting to come back, businesses are starting to do well, the unemployment rate is dropping?
Yes, food is costly, there are poor and sick everywhere; there are also very wealthy, healthy people. This has always been the case and always will be.
Obama's job is to see to it that the weakest among us are cared for, that the middle class becomes stabilized again and that the wealthy step up to the plate financially to help the country that has given them so much.
He won't succeed in all of it, but he will succeed in some of it, just as any other President would.
It's just going to take some time.
