The two biggest problems facing the middle class are wages and the economy. Democrats are the ONLY party to not only have a plan to fix both, but have actually tried and were blocked by Republicans.
One of the biggest problems the middle class / AMERICANS face is GOVERNMENT.
One example is Obamacare, a program that was promised not to cost a dime, to pay for itself, to lower the cost of insurance, to not cause people to lose their jobs or insurance, and promised if people liked their plan they could keep their plan...all in the name of 'helping'.
In the end not 1 promise was true: It did not pay for itself, did cost a tremendous amount, did not lower the cost of health insurance, caused people to lose jobs and insurance, and they lost the plans they liked.
Transgender bathrooms is another great example. The government stepped in, created a problem that didn't exists, divided the nation with it, then instituted a solution that no one liked....all to push their own minority-supported agenda.
Bringing in and defending disease-ridden, violent, illegals and 'refugees' who have no respect for this country, no respect for our laws, and no respect for the citizens paying for their housing, food, clothing, welfare, etc while Americans go with less health care, go homeless, go hungry...is yet another example.
Their government has spied on Americans, used the IRS to target them, has brought in and armed illegals and terrorists who have attacked, robbed, raped, & killed them and l has made them - illegals and 'refugees' - a higher priority than American citizens. Our government has defended radical Islamic terrorists and defended their religion while condemning and attacking Christianity and declaring Americans are the bad guys, a bigger threat than the terrorists that kill Americans.
Their government divides them racially and ideologically to the point of violence then wonders why there is so much violence...
...never taking credit for any of it.
The current existing government, run by these current elected politicians are one of the biggest problems this nation faces...but they have indoctrinated, partisan-ized, and divided us so much that we are unable to notice it because we are too busy fighting amongst ourselves over whose politicians are less corrupt, self-serving, criminal, scumbags.
