The lower middle class are the gentrified lower class. There is really no discernible difference between the lower class & the lower middle class. Both classes have a more primitive, down to earth approach to & philosophy of life. They work at similar jobs & have the least amount of education. One can aptly state that there is NO difference between the upper lower class & the lower middle class. Both are very authoritarian in terms of raising their children & are fond of using harsher forms of discipline, even corporal punishment on their children. The lower middle class has to struggle as the lower classes do to make ends meet. They send their children to public school as they cannot afford non-public schools. They can't afford to travel nor eat out. They also can't afford to have their children participate in cultural & intellectual activities as such are beyond their socioeconomic purview. They aren't socioeconomically comfortable & oftentimes live from hand to mouth like their lower class brethren.
