Bush tried to talk Dem's into investing some of OUR SS money and Democrats threw a conniption fit. Fact is Democrats used OUR SS money as a piggy bank, they "borrowed" OUR money, $2 trillion dollars of it and spent every last dime. They gave us worthless IOU's they can't pay back. If that happened in any private pension fund they would all be in prison.
One of the reasons Democrats never tried to increase contributions is because they know America will turn against SS and Medicare. These federal programs give them the power of control. Dependency has always been the Democrat strategy, and losing control over the two largest entities would strip them of nearly all power.
If I pass away before retirement, my nephew and niece get everything I worked for. They get my IRA, my bank accounts, my home and rental property, my big screen television, my valuable musical instruments. What they won't see is one red cent of what I put into Social Security. That fund dies with me, and all that money I contributed will go to strangers I've never met before instead of my family.
