They believe jobs are created and the economy driven ... by rich people getting richer.
In reality, in many ways, the opposite is true. Although of course there'd be such thing as 'taking it too far' (hence why their 'everyone should just stay home and collect unemployment then!' argument is a straw-man), generally speaking, the more that you take the accumulated money away from rich people and redistribute back down to the bottom of the food chain, the better is it for the economy.
Of course, with our capitalist system you DO need 'rich people' and through their wealth they do generate many, many jobs ... but there's a balance that needs to be struck in order for the economy to really thrive. A big reason the economy overall is struggling now is because SOOOO much of the money has accumulated at the top of the proverbial food chain, and those people are using the political power that the money affords them to buy off our government so it won't do anything substantial in the way of 'redistributing' their wealth back down to the bottom of the food chain.
Until such time as the average folks take back their government and start forcing the uber-rich to pay their fair share of taxes, we'll be stuck in an economic rut with lowering standards of living for the other 99% of people.
Prior to Reagan and the propaganda explosion of conservative radio and Faux Nooz and such, the majority of people probably understood these principles, but the rich have been hard at work promoting the idea that 'greed is good, rich people are why you get to have a job', so now 30+ years later, many many have no idea that this is largely bullshit.
