No end to subsidies for favored industries?

The $1 per gallon tax credit for biodiesel producers just passed the U.S. House and appears likely to become law.  The credit, which expired at the end of 2017, will be extended retroactively 2 years and forward for 3 years through 2022.  This tax credit started in 2005.  How long must the welfare continue?  Biodiesel producers are no different than most other businesses and industries in that they become dependent on subsidies and lobby heavily to prevent the subsidy from ever ending.  We need to pass laws that phase out all forms of energy subsidies, as well as subsidies given to other favored industries.  We need free-market capitalism, not crony capitalism.
