I do agree with petexdunn that politicians are the biggest criminals. They accept bribes from corporations, powerful groups and wealthy individuals.
There are more interested in working to these rich and powerful groups than workers and ordinary citizens.
Some of them want to cut Medicare and at the same time protect the rich from paying their due taxes.
For example GE paid no taxes for 2 years in a row. Just in 2010 they made $14 billion (pre-tax). And they pocketed $3 billion in tax credits.
The largest and the most profitable oil company, Exxon Mobil, paid no taxes in 2009. But they actually received $156 million in tax rebate.
The oil companies get about $6.2 billion is tax-subsidies from our government. There is more such situations
This means a hardworking family with husband and wife working two jobs, juggling with children in daycare and earns about $45,000/yr pay more taxes than both GE and Exxon Mobil combined.
The Republican party is trying to cut essential services provided by the government like Medicare and is pushing to tax breaks for the wealthy corporations and individuals.
I don't see any sense in what they are doing and it is criminal.
