There is a cost to all the freedoms you enjoy. It is unfortunate today's society has become "how much did it cost"? when it comes to the functioning of our government. Bottom line, anyone accused of a crime in the country has the opportunity to legal representation as they are innocent until proven guilty. The country spends way more on Public Defenders and to detain legal citizens than illegal aliens. It is unfortunate this country has an illegal aliens problem (and needs addressed) but if they get into trouble, our constitution which the government has to follow and citizens need to respect dictates what can be done. Period.
The country needs to improve laws in which it operates in the most efficient manner while keeping the values of the constitution for all persons in the US and that starts with tax policy. Have the proper tax policy that not only can be a stimulus to the economy but also pays for all the services the country needs. That is the first problem as we don't have a good tax policy due to this country being put on the wrong path since 1984 in this aspect.
I'm wasting my time writing this but regardless, it is the core problem of many other problems in this country.
