What gives them the right to do that at our expense? Why are you OK with congress being exempt from the financial affects of a law that they forced on the rest of us?
Their compensation isn't changing. This is where you're confused. Let's use round numbers to highlight this.
Let's say before they were making $80k in salary and received and additional $20k in healthcare benefits through their employer for a $100k compensation package.
Now, republicans want them to get their healthcare on the exchange, so they have that $20k healthcare benefit deleted from their compensation. But these people still need to buy health insurance. So they use their own money (the $80k) to purchase insurance on the exchange.
This is actually now a pay cut for all of these people so to even it out, their salaries are being adjusted to make it so instead of $80k salary and $20k health benefits, they are now getting $100k salary and $0 in health benefits.
So, as you can see, the total $ amount hasn't changed and nothing is changing for us the tax payer who pays their salary. Why should these people have to take a pay cut for some ridiculous grand standing by politicians?
Get it now?
