When the rich pay a smaller portion in taxes than those far poorer than they are, there's a problem. The rich sure as hell aren't getting any poorer anytime soon. They'd rather pad their own pay check than increase wages for the workers they already have or hire new ones.
Obama stabilized the economy and the economy is recovering by all economic reports. It's just not fast. The wealthy's obsessive hoarding and inablity to share or support their nation's lowest who buy their goods and services is rather shocking. The small tax increases would not be enough to destroy anything. If you're making over %200,000 and your taxes go up by as much as 5%, you will not be hurting for anything.
