The fact that 47% pay no Income tax should tell you that wages are DOWN and/or people aren't working. Romney is totally correct that if you are at that income level, you are probably depending on some assistance. Common sense says that we have 2 routes to fund the government- either expect "the rich" to pay more or to bring more of the "lower" income people onto the tax rolls. The PREFERABLE way to to have people working and far less strain on the government to feed, clothe, and shelter people and working to provide their OWN WAY.
The former is Obama's way and more people dependent on government and a nation where we "run out of other peoples money"- Socialism. Romney's way is a STRONGER America where everyone contributes to the services.
