So, in your estimation, would that be "better" or "worse" than "you cannot get a visa to come to the US and start a company at all, ever" (the status quo)
regardless, it's also not the case that all other backlogged visas are of higher priority than new visas. if there is a zero-sum game to be played, priorities could well be reviewed for all types of visas.
your argument for not approving this legislation seems to revolved solely around the backlog issue. there are other better ways to solve that problem than by simply stonewalling all other visa legislation.
