I always think in terms of questions which go unasked in debates like this. Here are only a few of them:
Is a person earning $1,000,000 a year worth more 17x more as a human being, as part of our human society, than people who earn $60,000 a year? Is their work needed 17x more than that lower-income worker?
Is a person who earns nothing, say a child, or a stay-at-home mom, or a severely handicapped or ill person, or a person who's been desperately seeking work for two years, or a retired person who worked for 50 years, worth less as a human being? Are people worth less if they were born or married into a poorer family and not a wealthier one?
Does a CEO in a profitable company, earning 400x more than his secretary, have more personal worth, or is more loved by his Creator, than the mail-room guy? Does he really, when all values are considered, have that much value to anybody besides investors in the stock market?
Does making a profit on money and investments (capital gains) require labor, like a electrician's or a day-care worker's income requires labor? Is it more or less valuable to society? Do school teachers, ditch diggers, truckers, farmers, waitresses and cashiers add anything of real value to our society? What if they all suddenly disappeared? Do their incomes accurately reflect their value?
Does an electrician's or day-care worker's life entail less actual "risk" than a venture capitalist's life? Isn't economic survival downright risky for those who barely make ends meet from one month to the next, those who could lose everything in the event of one more economic blow, one more medical emergency? Weren't their homes, livelihoods, and retirement accounts put at risk by people with all kinds of money in their control, and the power to make terrible decisions with our money?
Income disparity is growing. A smaller proportion of the general public is doing well every year. Every year, this nation is more closely approximating economic conditions in the Third World, where a small, elite class holds all the power and money, a huge underclass does most of the work, children get poor educations and grow up with little hope, go to bed hungry, and large numbers of people live off the economic grid simply to survive.
Why should this not be all of our business?
Afterthought: My daughter is in medical equipment sales. She works her butt off, jumps through flaming hoops, meets impossible quotas. She makes a great deal more money than I do, and I'm proud of her. And I also sacrifice deeply to make my life as an illustrator/editor for a small non-profit publisher possible. I get notes from students and teachers every month who love my work and are grateful that we make learning fun. And notes from teachers and homeschoolers, grateful that we make our materials affordable.
My work may pay 1/4 of my daughter's, but it is at least as valuable to society. And the structure that allows her fabulous income is driving up the cost of medical care, putting more and more of it completely out of reach for those of us who earn less. There's something seriously wrong with that picture.
