I don't know if there's much that is genuinely more blind about conservatism in general than the way today's conservatives studiously ignore the political dangers -- the dangers to rights and liberties -- presented by a significant disparity in wealth between the rich and poor. As Plutarch was smart enough to observe 2000 years ago, no republic has ever withstood a great gap between its richest and poorest members. It's not even rocket science -- wealth buys power, and ambitious individuals will use their wealth to that end. Fifty years ago, you would not need to explain it to an Eisenhower conservative, but today's FOX conservatives have only an insipid understanding of this matter, if they possess any understanding of it at all.
I agree that we need a strong middle class.
And I believe that the vast majority of both conservatives and liberals also think we need a strong middle class.
It's just that we differ on how to achieve that strong middle class.
Raising the minimum wage is NOT a way to increase the middle class.
It will very likely increase unemployment and under-employment, and/or cause greater wage stagnation among the least skilled workers of this nation.
If Joe the boss has five minimum wage workers, and he is forced to increase their wages to a new higher minimum wage, he will almost certainly fire one of those five workers to offset his losses (increasing unemployment).
Or keep the fifth worker but cut the hours of all five (increasing under-employment).
And all of the workers will almost certainly not receive any raises any time within the foreseeable future, since the boss is now forced to pay those workers more than he believes they merit (increasing wage stagnation).
And since there is now less of a gap between the minimum wage workers and those making above minimum wage, the employees making above minimum wage suffer a perceived pay cut.
Those who were making say $10.00 above minimum wage now suddenly find themselves making say $5.00 above minimum wage.
Which, in the eyes of the more skilled workers, cheapens their value to the company.
After all, how valuable to the company can you be when the unskilled workers make nearly as much as you make?
Increasing the minimum wage does not lead to a bigger middle class.
