My understanding of the term "neoliberal" doesn't include relentlessly lowering taxes or shrinking government. Maybe you mean "neoconservative" or "libertarian"?
To me, neoliberalism is better characterized as balancing market and non-market approaches to addressing social problems (more market-oriented than progressives, more comfort with government intervention than conservatives).
Also, sorta weird to blame Silicon Valley attitudes for a failure of the Texas government. Yeah a couple of companies from SV are opening offices in Texas, but this problem has been at least a decade in the making and it's not like SV is a dominant force in Texas.
