this left/right middle class, lower class, higher class, 1% discussion is pretty much a huge bullcrap btw.
it all depends on what you believe in and who your clientele is...
if you believe in trickle down economics, you believe that the wealthy people will reinvest their money saved from lower taxes in new business and what not and it will trickle down to everyone else. data suggests that it might have been true at some point but doesn't work that way right now since economy works different now than it did say 70 years ago.
if you believe in multipliers, then you believe that a broad middle class, whatever that might be, will reinvest their money saved from breaks or given by someone further into consumption and you will have an economic boom based on consumption and what not. which is all cool, but....depends on how sustainable it is and shit also may hit the fan if too many people buy too much of the same goods, a bubble comes up etc. but evidence suggests here too that a simple government handout doesn't work well. schools, parks, stuff like that, work better.
the other issue is how much welfare and government support belongs to those below the poverty line and what not....again, debatable. some are for vouchers, others believe in infrastructure and service for them, like better schools in poor areas, etc. again, ideological issue, depends on your skin color, your upbringing, how much of a douchebag you are or are not in what you believe in.
all in all, as a matter of fact, if we take the United States as the prime case, the country has done best whenever it was quasi socialist or led by politicians with what one would consider left policies, and by today's standards and actually compared to his time too, Eisenhower was pretty left too, despite being Republican. (extended social security, interstate highway, new deal support, events in Little Rock)
most importantly though
