Infrastructure funding is a pro-business position. At this point, most of the infrastructure that the Democrats are seeking funding for is maintenance, the definition of "status quo".

So is minimum wage, despite all of the screaming. Minimum wages ensure the existence of a working class. When the minimum wage drops below subsistence, there are civil disruptions that are bas for business.

When the Democrats expanded health care, they did so using a plan devised by the Heritage Foundation. It works on free-market principles, of consumers purchasing insurance from private enterprise. It is also very pro-business, creating a larger class of potential employees who can be hired without employer-sponsored benefits.

Many democrats would indeed like a government-run universal health care plan. But it's not a majority of the party, which is indeed (as the OP said) dominated by the center-right.
