> I can't think of a single thing government has done to "roadblock marriage".

Land use restrictions, housing regulations, and zoning laws substantially increase housing costs. Affordable family formation is the major driver of marriage rates. Housing costs are the primary component of affordable family formation.

There are plenty of places where you can find affordable housing in the US. Are marriage rates the same there?

Marriage rates are substantially higher in the cheap housing Southeast, Midwest and Texas than they are in the Northeast and West Coast.

The marriage rate isn't different enough across these states to justify the argument of housing. In fact, most places where housing is cheapest isn't the place where marriage rates are higher than the national rate.

Oregon and Washington outperform many southeastern states, in fact they surpass every southeastern state, according to the US census. And while N-E and CA do have a lower marriage rate, it isn't that much lower.
