I'm not gonna take the time to detail all the idiosyncrasies, ins & outs and subtleties of "Texan Culture" and "Money, Power and Influence" in Texas but, for what it's worth, here's my very brief "Take":
Texas IS a "Business Friendly" State...That's why Texas is booming while most of the rest of the U.S. is still in a recession.
Texas also IS an "Individual Rights" State...That's why many of the largest judgments against Fortune 100 & 500 Companies vs. John Q. Citizen have been handed down in Texas "Country" Courts and have been upheld against Appeal.
Texas also IS a "Freedom of Religion" State...But, Church Leader = Corporate CEO are not a fungible concept in the Texan Psyche.
Texas IS, in many ways, a "Money talks, Bullshit walks" State...However, the dynamic of Power and Influence of "Money" in Texas has modifying elements, such as lying, cheating and stealing which are highly detested and heavily penalized (if caught). If you got your dough from questionable, sleazy or underhanded means it's less "valuable" and sometimes even "worthless" to most Texans.
Texas IS a Historically "Family, Friends and Footprint" State...Texans, most of the time, "Hang Together" with "Their Own" (figuratively and literally, LOL). What sorta Folks your Family is and how you treat your family, who and what your friends are and how you treat your friends and what your "footprint" is and that of your family, friends and ancestors makes your Money more valuable to the point that there are many Texans of "modest means" that their true "Texan Wealth" is far more Powerful and Influential than many Multimillionaires. Money coming to you from "dubious" sources can lower the value of your Money and lessen your "Texan Wealth".
Texas IS a "what you have done" State...The Money of organizations and individuals that have a History of doing good things for the economy, employing people, being good citizens, treating folks the "right way" and doing things the "Texan Way" is FAR more valuable than a Johny Come Lately Self Affected Show Boat Blowhard BS Artist with a fat wallet looking to "buy their way" into the "Club".
Texas IS an "Opportunity" State...For the most part, Texans welcome new Folks with open arms and extend to them the opportunity to find their way, proof & prove their metal and build a life. However, opportunistic "outsiders' usually get handed their hat pretty damn quick.
Texas IS not "Utopia", far from it...But overall, its a pretty damn good place to live, raise a family, work and pursue happiness, and most Texans are real serious about keeping it that way.

PS: I left out the part about Texan's History of standing up to Foreign Powers (like Washington, D.C.) as I don't want to get into a political argument.
