Why are there democrats in the US Congress that are against raising the minimum wage?

Because there are ares smart ones. Raising min wage just causes more inflation.

A higher minimum wage can result to the following:

-fewer employees

-fewer hours for current employees or removed perks like tips, free food/parking, etc.

-increase in prices of products or services sold

-greater purchasing power for workers with the revenue going back to businesses they patronize and products or services they avail of or purchase

-decreased interest in college education since minimum wage jobs are paid almost the same or can be more than what jobs requiring college education pay

In relation to the minimum wage issue, here's an interesting report: http://bitly.com/1n4lqIa .

Because, like conservatives, they want to ensure the raise in the minimum wage doesn't hurt the economy more than it'll help. There are two sides to every decision and humans are fickle creatures who rarely respond in the way we feel they should. Do you remember the "stimulus checks" that were supposed to provide consumers with extra money that they'd go out and spend to stimulate the economy? That failed even though it wasn't supposed to...people saved the money and paid bills instead of spending like the government expected and it didn't help anything. Imagine if you raise wages and that happens.

Probably because they either got elected in a red state and/or they need financial backers from the plutocrats.

Their infected with the evil of Conservatism.
