Being straight is cheaper than being gay

That's what Angela Merkel indirectly said some days ago, but is it like that in real? We shall see it.

Let's check:

1. If you are gay, you probably won't have children (unless you adopt one). Even you choose to adopt you don't need to spend money in doctors before the birth.
2. You don't need to pay the restaurant bill to be polite.
3. You don't have over-expenses with children and family.
4. Gay people take a better care of their image which increases the possibility of being hired.

Is Merkel envious? She still supports that straight people should pay less taxes than gay? Is that OK? Of course not, where is the defence of the equality of rights?
