This bill is not an Obamacare replacement. Tax breaks for the rich is not a lie, it is the very raison d'etre (look it up) for this bill.
The upper 10% didn't like the taxes in Obamacare, so the Republican plan repeals those taxes and makes up for it by cutting federal money for Medicaid. Most states won't be able to absorb the extra costs, so low-income people will get the short end of the stick.
